Ordinarily the above won't compile because 'foo' hasn't

If I run something like ./mysource.d (using rdmd shebang) it
returns the full path to compiled executable in /tmp folder (not
so useful I think!). Is there a way to have the path of source

Hmm I thought It can be done reading __FILE__ at compile-time,
but it gives me just the relative path.

Right, forgot about __FILE__.

Interesting question. I would have to do more tests with odd names, but
apparently both remove() and rename() have problems with directories
with a blank name.
Curiously, moving
I only noticed that rename uses MOVEFILE_REPLACE_EXISTING flag,
which can't be used with directories. Are you sure remove fails
too? If rename throws, remove is not called in your code.

I agree. Probably safest to add a new constant, to avoid breaking code.

Another small reason is to enforce decoupling between required
code and the rest of the library. Back when Phobos was all one
library, half the library was compiled into every program. The
runtime writes to stderr, the IO package relies on other
modules... Kind of like what happens now if you

Too bad, it doesn't mention anything about calling the functions
like in my example, and why some do/don't work. I'd hoped for
more.

On the same set of data? That's optimistic if one of the loops
