I have the strangest problem I've seen so far in Perl. Please let someone explain what is going wrong here:

The case is simple. I have a file to upload via HTTP (you know: upload button, use CGI and get the file). I've rewritten the original script to this:
#!/usr/bin/perl -w use strict; use CGI; $|=1; my $buffer; print "Content-type: text/html\n\n"; print "<html><body>"; my $req = CGI->new; my $filename = $req->param("filename"); $filename =~ m/(.*?$CGI::SL)*(.*)(?=$)/; my $localfilename = "$2"; open(FILE, ">$localfilename") || print "Could not open $localfilename +for output: $!<br>\n"; while (my $bytesread = read($filename,$buffer,1024)) { print FILE $buffer; } close(FILE); print "File saved as $localfilename (original filename=$filename)<br>" +; print "</body></html>";
the HTML file looks like this (most simple form of course)
<html> <body> <form method=POST encoding="multipart/form-data" action="http://blur/n +ewtest.cgi"> <table border=1> <tr><td>Filename: </td><td><input type=file name="filename"></td></tr> <tr><td colspan=2><input type=submit></td></tr> </table> </form> </body> </html>
When I run this code and select any file, the moment the 'open' is called, the value of $localfilename is erased. Originally I used FileHandle but to make sure the error wasn't in that module, I replaced it with the plain open statement.

Now the strange part: when I leave out the use strict; everything works fine and the value of $localfilename is preserved.

I'm at a new job here, and everyone here tells me 'use strict' is no good, and I'm trying to convince them of the opposite, 'cause I always use it, and really believe anyone should use it, but this is making my statement a bit hard to defend....
