An anonymous function type.
functionType ::= TypeAnnotation? 'Function' TypeParameterList? FormalParameterList '?'?
where the FormalParameterList is being used to represent the following grammar, despite the fact that FormalParameterList can represent a much larger grammar than the one below. This is done in order to simplify the implementation.
parameterTypeList ::=
() |
( normalParameterTypes ,? ) |
( normalParameterTypes , optionalParameterTypes ) |
( optionalParameterTypes )
namedParameterTypes ::=
{ namedParameterType (, namedParameterType)* ,? }
namedParameterType ::=
TypeAnnotation? SimpleIdentifier
normalParameterTypes ::=
normalParameterType (, normalParameterType)*
normalParameterType ::=
TypeAnnotation SimpleIdentifier?
optionalParameterTypes ::=
optionalPositionalParameterTypes | namedParameterTypes
optionalPositionalParameterTypes ::=
normalParameterTypes ,?
