The first thing that must be done is justify why all the other
alternatives that already exist are not sufficient, such that we should
invent something entirely new.

Larry Wall (inventor of Perl), for example, is an accomplished linguist
and has thought long and hard about the theory and implementation of
natural languages in the design of Perl.  I've created a few small DSL's
(domain-specific languages) in my day and I'm quite confident that I, at
least, couldn't do better than Larry.
