in reply to How to access outside variable

Since $a is defined in the same package - main - what happens is that the value of $a gets merely overwritten, variables in the same package are global to that package scope,

#!/usr/local/bin/perl print __PACKAGE__ ; print "\n"; $a=10; { $a=11; print $a,"\n"; print __PACKAGE__ ; }
look up __PACKAGE__ in perlmod and perldata, coping with scoping can be a good read as well..
