import std.algorithm: map;
import std.typecons: tuple;
int foo() {
    return 0;
}
void main() {
    auto bars = map!(n => tuple(foo(), n))([10]);
    auto spam = bars.front[1];
}


Compiling with:
dmd -O test.d


DMD 2.058head gives:

Error: variable __tup818 used before set

Note the lack of error line number.
