Please note that adding a new keyword will often result in breakage of
many existing programs.
when I've got a function like:
funtion do_something(from, to)
I'll got an error if "from" is a keyword.
Is there any serious programming language (except SQL) using "from" as
a keyword? If not, then it is highly likely that this word will be
freely and widely used as variable name and argument names.
