In the following snippet `format` is font-locked as the built-in
function, but it's actually a variable.

respond_to do |format|
  format.json do
    # ...
  end
end

This problem obviously exists for all built-ins, but it's not a big
issue in general, since most of them don't have names that are likely to
be used as variable names. Not sure if we can have a simple solution for
this problem without a parser, though. I guess we can have a check if
the built-in methods have arguments (as most of them have).
