More not-quite-FlightGear subject matter ahead. But I need advice:
Nasal needs a "character constant" syntax. That is, the ability to write an ASCII charactrer as a numerical constant. In C/C++, you use single quotes to do this (e.g. the token 'A' is just a synonym for the integer value 65).
(Brief background: I just added the ability to read and write individual bytes in a string with the  operator, just like you can for elements of the vector. Thus the need for character constants to which to compare those bytes.)
But Nasal can't do that, because it already uses single quotes for unescaped strings, something that will be really useful in the regular expression interface I am putting together.
At first I was thinking using #'A' since # represents a number already in most cases, but then again; how about just using a new function?
