assert with format considered harmful

[Ali Çehreli via Digitalmars-d]

If the generation of the error message throws, then the program receives 
a FormatException, not the most import AssertError:

import std.string;
void foo(int i) {
    // In this case a %s is forgotten but it could be any other trivial 
error.
    assert(i == 42, format("Bad parameter:", i));
}

void main() {
    foo(43);
}

So, obviously, assert message generation is not lazy. This is a WAT! for 
me but perhaps there is a good reason for it.
