compiles checks are just slightly to dumb

[crazymonkyyy]

void foo()(){static assert(0);}
unittest{
	import std;
	static if(__traits(compiles,foo)){
		"yay".writeln;
		foo;
	} else {
		";__;".writeln;
	}
}

Error: static assert: 0 is false

eh foo and foo; aren't quite the same

but i agree these checks are dumb and should never be used

some day we can finish making reflection great again

[crazymonkyyy]

are there more issues?(besides the syntax, oh my god) is it hard to just dig down one more layer?

this seems to work:

void foo()(){static assert(0);}
unittest{
	import std;
	static if(__traits(compiles,foo())){
		"yay".writeln;
		foo;
	} else {
		";__;".writeln;
	}
}

hello new person to summarize the discussion from the main chatroom:

1. the (current) correct method is:

void dummyfunction(T)(T t){
  auto a=t.length;
}
enum haslength(T)=__traits(compiles,dummyfunction!T);

2. T.length may be either a variable or a function

3. Im just complaining

are you looking to get involved?
