And a lot, regrettably :) , in Perl...

It's actually not so difficult to write cross-platform apps in C++,
probably not more than in any other language. (At least
Windows/Linux/Unix.) The few platform-specific functions you need in
non-GUI apps are easily wrapped -- and doing this takes usually about as
long as understanding what VM wrappers do differently on different
platforms.

If you need cross-platform GUIs, a decent cross-platform framework is
quite helpful anyway, no matter the language. Then there's deployment
and integration with the native system, which isn't solved by VMs either
(and may be complicated by them).=20
