Function Literals

[Falk Henrich]

Hi!

I'm just experimenting with delegates and came across

http://www.digitalmars.com/d/expression.html#FunctionLiteral

where one finds this example:

int abc(int delegate(long i));
void test()
{   int b = 3;
    abc( (long c) { return 6 + b; } );
}

My question is: If the compiler can infer the return type of the anonymous function, how come it can't infer the type of the parameter c? Forgive me if this is too stupid a question, but I thought: if the compiler knows the signature of abc it has to be clear that c is of type long.

Is it possible to simulate a syntax like

abc( (c) { return 6+b; } );

using templates / mixins?

Thanks for the advice!
