Mathematica: Webel ADT pseudo classes: 'Q: Do I have to use these EX$Val scalar "atom" thingies and the EX$Row, EX$RowList, and EX$RowMap? Can't I just use Wolfram Language Lists and Associations?' A: Of course you can also use the basic Wolfram Language!
Mathematica: Webel ADT pseudo classes: An EX$Val has concise methods for testing the type of its wrapped '$$' value: isR, isI, isB, isQ, isS. These may be used in ADT "constructor" type tests.
Mathematica: Webel ADT pseudo classes: The validity of the type of a wrapped '$$' value of an EX$Val may be checked in ADT "constructors" which have type checking utility support. This strategy has been chosen over sub-types of EX$Val.
Webel: SysML4Mathematica: An '@*~' prefix in a @pseudo function (OpaqueBehavior or Activity) represents a cast from any expression to a Type. Example: '@*~OpenerView' casts from any expression to an OpenerView. '@Type~' casts from a specific Type.
Webel: Mathematica: CONVENTION: A '$sig$f$' prefix indicates a String signature helper for a function (or for a "method" of an MTools class or a Webel Abstract Data Type (ADT) pseudo class).
Webel: Mathematica: CONVENTION: A '$doc$' prefix indicates a formatted documentation String helper. A '$doc$arg$' is for an argument, a '$doc$opt$' is for an option. A '$doc$ String may be used to create ::usage documentation via docF.
Webel: Mathematica: CONVENTION: A '$t$' prefix indicates a String help holder with a "pseudo type" indicator (for human friendly documentation only). Used by the Doc`, HelpF`, and HelpO` packages.

Webel: Mathematica: CONVENTION: A function's description (but not its signature, arguments, or options) may be captured as an '$info$f$' Stringhelp holder for use by the Doc` package for ::usage generation and the HelpF`& HelpO` help registry packages.

Webel: Mathematica: A help Rule 'rule$opt$' for an '$opt$' (option) accepts keys: '$k$help' (required), '$k$def' (required), and optional '$k$warn', '$k$tip', '$k$lab' (a label), '$k$type' (indicator only), '$k$mult' (SysML multiplicity), and '$k$pat'.
Webel: Mathematica: A help Rule 'rule$arg' for an '$arg$' (argument) accepts keys: '$k$help' (required), '$k$def' (required if $k$req = True not given), '$k$req' (True if $k$def not given), '$k$warn', '$k$tip', '$k$lab', '$k$type', '$k$mult' and '$k$pat'
Webel: Mathematica: CONVENTION: An '$opt$' (option) or '$arg$ (argument) help holder may be have an associated (typically short) '$lab$opt$' or '$lab$arg$' label help holder for use in GUIs and views.

Webel: Mathematica: CONVENTION: Where keys of Associations are Strings they are encapsulated as variables prefixed with '$k$' (promotes DRY and has many advantages, such as IDE prompting). Direct use of "Strings" as keys is WET and strongly discouraged!
Webel: Mathematica: CONVENTION: Argument help holders use a String variable with the prefix '$arg$', a related '$info$arg$' String, a 'def$arg$' default value expression and/or 'req$arg$', and optional '$warn$arg$', '$tip$arg$, '$lab$arg$', 'type$arg$'..

Webel: Mathematica: CONVENTION: A prefix 'sym$' indicates a markup variable "symbol" for a documented variable. It need not be a String, but each referenced part MUST be a String - not a Mathematica Symbol - to avoid namespace clashes!
