Indeed this is a situation in which turning on warnings would have solved the problem for you: `$ perl -we '%a=($bob => "foo")' Name "main::a" used only once: possible typo at -e line 1. Name "main::bob" used only once: possible typo at -e line 1. Use of uninitialized value in list assignment at -e line 1.` [download] See in particular the last line. But then if had also turned on strict `$ perl -Mstrict -e 'my %a=($bob => "foo")' Global symbol "$bob" requires explicit package name at -e line 1. Execution of -e aborted due to compilation errors.` [download] So, to put it briefly: do it!	[reply] [d/l] [select]
