Subject: [ruby-talk:7790] Re: Regex array subscripts

I'm just a Ruby-nuby and sparse documentation has me trying to construct
my own (deeper) explanations for why things work the way they do.  wrt:

"one 123 two"[/\d+/]   =>  "123"

even more simply we have:

"one 123 two"['e 1']   =>  "e 1"

So, what is confusing is when the documentation says:

"Arrays are ordered, integer-indexed collections of any object."

It appears that an integer index is only one way of accessing array
elements.  Which is what had me confused, because i was led to think
that /\d/ and /\d+/ both return an (the same) integer.  But apparently
they return the matched string, which works just fine as an array
index.  Wierd.
