It's known, but I don't know that it qualifies as a bug. When you
use the two argument form of open, Perl is looking for both the
filename and mode, concatenated together, possibly with spaces
separating them. Since your file ends in a space, you can't use this
shortcut. In reality, you should NEVER use this short cut.

That's an awfully long time.

The functionality is there for a reason, and sometimes it's appropriate
to use it. Admittedly, that's not very often, but it's more often than
never.

It's there to make modern Perl compatable with old Perls. The only
justifiable reason I can think of to use it is to allow your user to
specify a pipe instead of a file name when you ask for a file. And if
that's something you want to do, I'd suggest you're programming a
pretty massive security hole.
