This bug is invalid because of the way template instantiation from string
lambdas works.  Instantiating map with q{a + 1} produces a completely different
type than map instantiated with q{a + 2}, and therefore storing them in an
array should not be possible.  Take a look at how Map and
std.functional.unaryFun() work.  Also, to illustrate my point, note that the
following code works:

import std.algorithm: map;
void main() {
    auto r1 = map!q{a+1}([1, 2, 3]);
    auto r2 = map!q{a+1}([1, 2, 3]);
    auto a = [r1, r2];
}
