It's perfectly legal code, so the best a compiler can correctly do is give a warning.
Some C(++) compilers understand printf and will warn if the format string doesn't match
the arguments, but even this is rare AIUI.
To enforce well-formed format strings at compile time would require it to be made a
language builtin. Or maybe template metaprogramming can do it.
import std.stdio;
void main() {
writefln("%d", "hello");
}
And it outputs:
['h', 'e', 'l', 'l', 'o']
Is this good/expected/acceptable/buggy?
It certainly should either throw an exception or generate more sane output such as Andrej
is getting. What DMD version are you using?
