Case scenario: I want to run a perl interpreter over a socket, sort of perl shell. It's not all this process does, so I poll the interpreter socket(s) with select() and eval everything I sysread() from the sockets. I hook $SIG{__WARN__} and syswrite $@ and warnings to socket. So far, so cool... but what if I want to redirect stdout of this eval'd code to socket too?
local *STDOUT=$fh;

should work - I think - but it doesn't. I can't use print() on sockets (I tried). I don't want to make all remote code use syswrite instead of print - so, I try to redefine print() to a wrapper and eventually syswrite. But, it appears I can't do that. I could redefine chdir() just like man perlsub said, but the very same code with print() doesn't work.

What am I doing wrong? Any suggestions? Since this is a practical problem, anything fixing the problem of print() in eval'd code going to socket would be helpful.

Also, note that this has to run under cygwin perl, so some platform-dependent tricks may be unavailable. Recent versions of perl, however, aren't a problem.
