Subject: lexer/parser: o Renaming the ASSERT_K token to ASSERT. o Fixing a bug
 in the NAME regex where underscored where not allowed in certain names. o All
 ASSERT statements use string instead of NAME. o Improving STRING_ANY, allow
 many non-quote tokens instead of just one. Can probably replace the entire
 string rule with STRING_ANY now. o Fixing naming of '!', "~" and "?"
 operators. Ld: o Implement support for multiplication and division operators.
 o Better error messages.
