It would've been nice to know what that use-case is, rather than just 
knowing that you had that use-case.

I'm having a hard time thinking of something where I don't a-priori know 
what type I expect to get and would need to inspect the value to make a 
decision.

I see how having a function that safely coerces a string into an int, 
returning null if coercion fails, basically intval() with better error 
handling and taking only `string`s, could be useful, but that's not what 
is being asked here.

Best regards
