"With great power comes great responsibility" -- said that, please allow
yourself to understand the following example:
("abc01".."abc99 ").to_a
Observe this little (which may happen) mistake after "abc99". That is the
easily over-looked single space.
If you do that in your manifest, let say ... by accident... then your
Puppet Master will more likely become a happy candidate for OOM Killer to
consider :)
Do you know if, after editing a .rb file, I have to force some kind of

No, there is no need to reload, but this is not the solution. Instead, in
order to guarantee safe execution and also provide desired effect a
different approach can be taken: You can scan for how many string-encoded
digits you can fine within start of the range, count then and then based on
this counter collect (or map if you like Perl so much) generated range with
relevant substitution. If done right, then it will allow you to
zero-padding of any size at any place in the string e.g. test00, 00test
this00test, etc ...
I will update my version f range shortly to do precisely that.
