in thread How to check if a word is reserved

That's cool! I never knew about that, but I do have one question.

I've got the following lines in my keywords.h file:

#define KEY_x 249 #define KEY_xor 250 #define KEY_y 251

xor I get as that's a function, but x and y are reserved? What gives?

There is no emoticon for what I'm feeling now.

    It's hard to spot when they look paired like that, as they do wholly different things. Proof by example:

    perl -e 'print "x is a reserved word!\n" x 3;'
    perl -e '$a = "y is a _synonym_ for tr\n"; $a =~ y/_//d; print $a;'

    perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'

      Yes, now that you show me that, I see. That hadn't even occured to me last night. Must have been too tired. Thanks!
