This is a bug report for perl from lmai@mytum.de,
generated with the help of perlbug 1.34 running under perl v5.8.1.

[Please enter your report here]

Greetings!

% perl -Mstrict="}" -e1
Unmatched right curly bracket at -e line 0, at end of line
syntax error at -e line 0, near "q{}}"
Execution of -e aborted due to compilation errors.

The following patch fixes the above problem:
% perl-patched -Mstrict="}" -e1
Unknown 'strict' tag(s) '}' at -e line 0
BEGIN failed--compilation aborted.

This may break some JAPHs but I think it's the correct behaviour.

HTH
Lukas Mai
