Shouldn't it be called only when exception is thrown, to speed up the case
when the exception is not thrown?
In C/C++ in the presence of the preprocessor a string
char foo[] = "\
long\
string\
without\
linefeeds\
";
Is translated by the preprocessor to
char foo[] = "longstringwithoutlinefeeds";
is there a similar mechanism in D? Or should I do...
string foo =
"long"
"string"
"without"
"linefeeds"

As for allowing 'X'w, I think the rationale is that a cast will
get you the same result (not so with string literals).
OK. I have desired those char suffixes for years, so now I have

Thanks. I suspected it but i wanted a formal reference. the
logic, though little bit cleared by you is quite obvious. But
don't waste time, if you can not tell from a scratch that this
is clause x.y.z of the Standard, sorry, Book.

Cause i'm a C++ programmer and there is no such thing as module

That directly initializes the variable at compile time, meaning that whatever
