A word of advice to dumb Americans trying to go to Canada on Rails: Bring proof of citizenship and a letter saying that you're not working in Canada! I didn't bring either of those two items, so I got stuck at the border crossing for an hour while one of the ThoughtWorks offices fixed things up for me.

Here is a small snippet of code showing how I kept my mind occupied while waiting at the border. (I hope at least some of you will recognize the following syntax and be very curious what I'm up to... hehehe.)

CONSTANT=[A-Z] [:jletterdigit:]*
IDENTIFIER=[:jletter:] [:jletterdigit:]*
SYMBOL=[:] [:jletterdigit:]+

{CONSTANT}   { return RBTokenTypes.CONSTANT_LITERAL; }
{SYMBOL}   { return RBTokenTypes.SYMBOL_LITERAL; }

{WHITE_SPACE_CHAR}+   { return RBTokenTypes.WHITE_SPACE; }

{END_OF_LINE_COMMENT} { return RBTokenTypes.END_OF_LINE_COMMENT; }

{INTEGER_LITERAL}     { yybegin(DIV); return RBTokenTypes.NUMERIC_LITERAL; }
{FLOAT_LITERAL}       { yybegin(DIV); return RBTokenTypes.NUMERIC_LITERAL; }

More about this code later.
