I'm writing a lexer for Rust, which follows Unicode conventions for legal 
identifier start- and continue-characters. It appears that these are specified 
by Unicode TR's #31 and #44. Anyone object to my adding code to parser-tools 
that automatically extract said character properties from the text file 
provided for the purpose by unicode.org? I've poked around, and it doesn't look 
like this currently exists in... the places that I looked, anyway.
