(unparse ..args)
  args: zero or more arguments (any type)
  returns a str

Losslessly converts GameLisp data into a string.

This function is similar to str, but it will fail if it receives data which can't be losslessly represented as text. This includes...

• Values which belong to a primitive type other than nil, bool, int, flo, char, sym, arr, str or tab.
• Reference cycles.
• Symbols generated using gensym.
• Symbols which would be read back in as a number or abbreviation, like (sym "5").

The result of (parse-1 (unparse val)) is guaranteed to be eq? to val.
