It can be (I'm reliably informed by a linguist sitting
a few desks away), in that someone might be analysing the
text of (say) a motoring magazine. "The A1-M1 link road"
(for UK readers) or "a V6 Engine...or I could have had a V8".
where any comparisons don't make sense without the numbers.

So what is the best way to parameterise these to allow
turning on/off the removal of numbers?  And while
we're at it, turning on/off the removal of hyphens or
other possibly-word-forming characters?
