class Myst::AnonymousFunction
- Myst::AnonymousFunction
- Myst::Node
- Reference
- Object
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'
