Where the variable is defined that is referenced in the

So:

if the uses parma is 'scope':
void uses(scope void delegate() dg);
will it be not alloc memory?
I test it , if use scope it will not alloc memony.
import std.stdio;
void call(void delegate() fun)
{
fun();
}
void call2(scope void delegate() fun)
{
fun();
}
void main()
{
int a = 10;
// call((){writeln(a);});
call2((){writeln(a);});
}
dmd -vgc ./t.d
it will not print anything.
if use call:
void main()
{
int a = 10;
call((){writeln(a);});
// call2((){writeln(a);});
}
dmd -vgc ./t.d

./t.d(13): vgc: using closure causes GC allocation
