I would rather minimize the invention (and consequential memorization) of
special keywords. Parsing them is not made quite as trivial as it seems
(especially when alternate languages are involved). Structured text had the
favorable trait of being very easy to remember. Parsers are built using
formal definition of special case rules anyway. Where special casing based
on context becomes non-obvious to remember is where I would draw the line
and resort to literal keywords.
