Re^3: Defining a sub within a sub: OK?

Subroutine names are package variables and therefore not "globally scoped". Only certain Perl variables fit the definition of "globally scoped".

the sub level1 is defined within an explicit scope, not within a code block.

Basic BLOCKs

What I meant by 'globally scoped' was 'accessible from any point of execution within the program', and package variables do fit this definition. I agree with jwkrahn's point about the 'code block' (as defined in the referenced discussion of blocks). What I thought was meant was a 'code block' of the sort associated with sort and other such built-ins, e.g., `my @sorted = sort { $a <=> $b } @unsorted;` (Hang on, I may be experiencing a 'lobe block' ... )	[reply] [d/l]
