Constraints simplification

Remove parentheses from constraints such as number(blank: false) to number blank: false:

Search: (\w+)\(([^)]+)\)$
Replace: \1 \2

Method call simplification

Replace all method calls of the form foo('bar', 5) to foo 'bar', 5:

Search: ^([ \t]*[\w.]+)\(([^])]+)\)$
Replace: \1 \2

In Vim use this command: :%s/\(\w\+\)(\([^])]\+\))$/\1 \2/gc.

It doesn't replace occurrences such as foo([1, 2, 5]) because the replacement foo [1, 2, 5] would be interpreted as property access.
