"10,000" -> 10000

Rubies:

Besides .gsub(',', '').to_i, what's a good way to un-delimit a big number?

Ideally, it should be the reverse of Rails's number_with_delimiter...

I would be quite happy with gsub, but if you want another shot on it
you might do
scan(/\d/).join
or
scan( /[+\d-]).join

str.delete ","

If you like to check the syntax:

str.gsub /,(\d\d\d)\b/, "\\1"

Txbut - imagine if number_with_delimiter magically imbued your string with
locale awareness (like the C++ imbue do).

We got anything high-level like that? Some cultures reverse the roles of commas
& dots. (I don't rly need locales myself; I'm just annoying the envelop here...)

The near-term winnah! I didn't know .delete() would do them all...

It's for Cucumber tables, so if it's in-house, I don't need to annoy my clients.
If I could get them to author the tables anyway...

I think the real issue here is getting those cultures to use commas and
dots correctly.
