class Myst::AnonymousFunction

Overview

A shorthand function definition with multiple clauses. AnonymousFunctions are most commonly used to define complex behavior in place of a block parameter for a function. Clauses are defined using a "stab" (->), followed by a parenthesized parameter list, then a clause body wrapped like a normal block (either with {...} or do...end).

An anonymous function must be given at least one clause to be valid.

'fn' [ '->' '(' [ param [ ',' param ]* ]? ')' [ '{' | 'do' ] body [ '}' | 'end' ] ]+ 'end'
