in thread eval not behaving like I expected... why?

I think you're forgetting that my produces a lexical variable that isn't attached to a package namespace.
That being the case, (and I'm agreeing with you) why does this work?
That's ripped right from the man page for Inline::Filss and it works! Try it!use Inline::Files; use Data::Dumper; open CACHE or die $!; # read access (uses $CACHE to locate file) eval join "", <CACHE>; close CACHE or die $!; print "\$var was ’$var’\n"; while (<>) { chomp; $var = $_; print "\$var now ’$var’\n"; } open CACHE, ">$CACHE" or die $!; # write access print CACHE Data::Dumper->Dump([$var],['var']); close CACHE or die $!; __CACHE__ $var = 'old value';
