Thanks. I was trying to get the return type of lambdas. I was
trying the following and got an error. I was using dpaste with
dmd 2.070
writeln(ReturnType!(a =(a *a)))
Error: template instance f662.main.ReturnType!((a) => a * a)
does not match template declaration ReturnType(func...) if
(func.length == 1 && isCallable!func)
Ah, I see. I'd like to test something; can you please change
`(a) => a * a` to
`(int a) => a * a` and post the results?
Thanks for the reply. But the issue was about knowing the type of
lambda in map. Most people won't enter the type of argument in a
map. Is there a way to detect the return type will be non void.
The return type is not much necessary here I just need to verify
the function is not void.
