LOOKING UP WORDS
Is your word a reserved word or a built in library?
Is it part of standard Lua? If not it may be part of
RiscLua, so see the libraries riscos
or lpeg.
Remember that unreserved names are not fixed to the extent that they may be in other languages.
For example, if a library called foo contains a member
called bar then the value foo.bar
may appear simply as bar when the syntactic environment has
been set to foo.
