This is a bug report for perl from nick@ccl4.org,
generated with the help of perlbug 1.35 running under perl v5.8.8.


-----------------------------------------------------------------
[Please enter your report here]

$ ./perl -le 'print uc *foo; print uc *bar . ""'

*MAIN::BAR

I assume that this is a bug.

Blead gives

*MAIN::FOO
*MAIN::BAR

but it has a different typeglob implementation.
