comments are written with # -- anything after a # is ignored, until the end of line
reverse-comments are written with ^C -- anything before the two-character sequence ^C is ignored, until the beginning of the line
allow types to have juxtaposition as an operator. now on strings define the juxtaposition s t to be the string consisting of s followed by a single double-quote followed by t
now you get double-quote escapes for free! need to write the string co"host? write it as "co""host". in other words, escape your double-quotes by doubling up :)))
