A syntax option (function types versus arrays)

[Peter Levart]

I think we don't need statement lambdas if we allow expression to be preceeded by statements (like in block expression of CfJ0.6b):

Lambda:
  '(' FormalParameters_opt '->' Statements_opt Expression ')'

for void lambdas "void" keyword could be defined as expression of type void:

(->void) lambda = (-> System.out.println("Hello!"); void);


Regarding arrays of function types, this syntax:

FunctionType:
  '(' ParameterTypes_opt Throws_opt '->' ReturnType ')'

is perfectly combinable with array type syntax.
