Re^2: namespaces and variable initilization with require 'file'

Did you really mean to use the word 'modules' for both kinds of files? I guess in any case that you didn't mean that require can only be used on files with a package directive, because that's certainly not true:

$ echo 'print "Included a.pm\n";' > a.pm
$ perl -e 'require a' # Included a.pm
[download]

works just fine for me. I understood a big difference (though by no means the only one) to be between whether you want to allow the file to be read multiple times, in the sense that

$ perl -e 'require a; require a' # Included a.pm
$ perl -e 'do "a.pm"; do "a.pm"' # Included a.pm\
                                 # Included a.pm
[download]

do different things.

The repeated use of "modules" was a copy and paste error. And right, I wasn't talking about the abilities of the respective commands, but their purpose. `do` executes a file. So does `require`. The difference is that `require` will only execute a file once per run, so it only makes sense to use `require` for files that load a module.	[reply] [d/l] [select]
