Julia: Combine `contains` and `ismatch`?

[simonbyrne]

ismatch and contains do basically the same thing, except the first takes a regex pattern, the second a string pattern, and the argument order is switched.

Can we combine them, and if so, which one should we keep?

(let's try a vote by thumbs up)

contains

• matches the argument order of replace (which already accepts both regexes and strings)

[simonbyrne]

ismatch

• begins with is (making it easy to find by tab completion)
• matches the argument order of match
