This D2 program is OK (dmd 2.048), the math import is required to perform the
^^:
import std.conv: to;
import std.math;
int foo(int b, int e) {
return b ^^ e;
}
void main() {
foo(5, 3);
}
If I remove the math import the program doesn't compile:
import std.conv: to;
int foo(int b, int e) {
return b ^^ e;
}
void main() {
foo(5, 3);
}
But the given error message is bad:
test.d(3): Error: undefined identifier module test.std
An error message like this is better:
test.d(5): Error: must import std.math to use ^^ operator
