`alt!` + `map!` + `call!` strange behavior about nom HOT 5 CLOSED

Hi! Thanks for your report, I'm on it

from nom.

It should work with that commit. You do not have to use call! in map!, flat_map! and others like these, they use it already.

from nom.

Now map! does not require call! wrapper for expression. But map_opt! and map_res! still require it.

For example:

Ok:

named!(parse_u32<&[u8], u32>, map_res!(map_res!(digit, str::from_utf8), call!(|s: &str| s.parse::<u32>())));

Err:

named!(parse_u32<&[u8], u32>, map_res!(map_res!(digit, str::from_utf8), |s: &str| s.parse::<u32>()));

from nom.

ok, I'll fix them as well

Hi!

I think 94fbe95 will fix it for map_opt!and map_res!
