I noticed these files all had strings such as "", " ", "_" that were
allocated each time some common methods were called, over 1000x on a
page in my app. This comment freezes all of these strings such that
they're only allocated once, saving many KB of memory allocation.
In most official-looking places, the gem is refered to as "SimpleForm",
rather than "simple form", "Simple Form" or "simple_form". When we're
talking about the gem, use "SimpleForm". In code, keep "simple_form".
Eliminate all instances of "simple form" except when capitalized in
deprecation messages.
