Why calling a lambda in expressions causes an error

[xbyte3]

Code:

const A = function() {
    return 1
}
B = A() # <- Error: Cannot use void in expression position

Why calling a lambda in expressions causes an error "Cannot use void in expression position"? I think this is a bug.

I'm guessing it's because your function doesn't have a return type?

Lambda calls require using a type designator. Just how it was made.
