Section 4.1 (Lexical Conventions) says:
"The following words are reserved, and cannot be used as identifiers:"
[list deleted]
Just to make it absolutely clear, it should also say: "identifiers are
represented by the terminal symbol name in the grammar.".
What tripped me up was trying to use "repeat" in a table constructor:
{ repeat = "AUTO", blah = "whatever"} because I didn't realise/forgot
that repeat was a keyword. But now I think about it, it's ever so
slightly bogus to impose a non-reserved keyword restriction in table
constructors because they're supposed to be sugar for
["repeat"] = ...
but I can obviously see why it's like it is.
