true if X is a function, false otherwise
static void func(){} static assert(isFunction!func); struct S { void func(){} } static assert(isFunction!(S.func));
Use isFunctionPointer or isDelegate for detecting those types respectively.
Detect whether symbol or type X is a function. This is different that finding if a symbol is callable or satisfying is(X == function), it finds specifically if the symbol represents a normal function declaration, i.e. not a delegate or a function pointer.
