It's too close to:
p "\244\242\244\244".chop @jcode

That's an ArgumentError, but it would be a valid call to chomp, for 
instance.

FWIW, I think I like the block-style idea, but rescue-ish is good, too.

def foo # or any block-starting thing
  # global namespace
  using my_namespace
  # specific namespace
end
# global namespace again

and you could also allow a trailing using to apply the namespace to the 
whole expression:

"foo".reverse.capitalize using my_wacky_string_namespace
