No, perlvar sayz:

$@ The Perl syntax error message from the last eval() operator. If null, the last eval() parsed and executed correctly (although the operations you invoked may have failed in the normal fashion). (Mnemonic: Where was the syntax error "at"?) Warning messages are not collected in this variable. You can, however, set up a routine to process warnings by setting `$SIG{__WARN__}' as described below. Also see the Error Indicators entry elsewhere in this document.
So that's something different (it returns the syntax error). use $ret=eval... for return values.

And indeed, that redirection won't work under windows. But maybe a real shell helps in that respect: try cygwin or bash4win.

Oh, and fixed those quotes. Sorry about that.
