Libraries Std.Symbol
Types
T
Inherits from:Std.Function.T
The type of all symbols (a.k.a. multimethods).
ArrayT
NoMethodMessageT
An instance of this type is sent when no signature is found to match a method call.
Constants
Default : T
Default is called whenever a symbol call fails to match any signature. I.e. if symbol has no signature matching args..., then the call symbol(args...) is then treated as Default(symbol, args...). Since Default is an instance of T, this allows for a certain degree of meta-programming.
If Default itself fails to match a signature, then it sends an instance NoMethodMessageT.
If Default itself fails to match a signature, then it sends an instance NoMethodMessageT.
