"global variables" are names in the outer scope for nested functions, so that
doesn't solve the problem, and generally kills C compatibility of D.
Time ago I have suggested a keyword like uses or outer, to explicitly list what
names a function uses from the outer scope:
int z;
int bar(int k) uses out z {
int y = k * 2;
int foo(int x) uses in y, out z {
z = y * 2;
return x * y;
}
return k + foo(k * 3);
}
But this example is a mess already, better to not encourage the usage of such
coding style.
