Arr subtract

Hello

Thanks for the answers!

How can I do it with an OPTIONAL blocK?

Meaning:

how can I forward the block as arg to another method?

def mymeth(var, &block)
arr.find (var, &block) ... # does not work! # how to "tranlate"
the args to use them here?
end

···

---
I assumed arr.delete{} would delete if the expr is true. Would anyone
expect what arr.delete is doing??

thanks
