'string' - 'str' as a shortcut for 'string'.gsub('str', '')?
Sorry if this has been brought up before, but I couldn't find anything.
I love how we can substract arrays (
[1,2,3] - [1,2]). Does anyone else think the same syntax would be beneficial for Strings?
Some possible scenarios could be:
'string' - 'str' # Remove substring 'string' - ['s', 't'] # Remove a set of characters 'string' - /^st/ # Remove by regexp

I do not doubt that it can be useful. One advantage of your proposal is that it
is very short and succinct.
Personally, though, I prefer .gsub() or .gsub!(), and .delete or sawa's suggestion.
I don't have anything against "-" per se and as you showed that Array has the
method, the same could perhaps be used for class String. But this may be a design
decision (I don't know).
But perhaps there is a design consideration matz considered (or not, I really do
not know). It may be best to ask matz about - for class String.
I would also recommend to contrast your proposal to what sawa suggested; for
example, you could propose - to be an alias of String#delete, or something
else. That may be helpful or perhaps simpler. (I myself really don't know)
