module Bootsnap

def rb_get_path(fname)

But we only use it for non-MRI platform.
The native version is very intricate and may behave differently on windows etc.
This is a semi-accurate ruby implementation of the native `rb_get_path(VALUE)` function. 
def rb_get_path(fname)
  path_path = fname.respond_to?(:to_path) ? fname.to_path : fname
  String.try_convert(path_path) || raise(TypeError, "no implicit conversion of #{path_path.class} into String")
end
