Below is an example grammar that can be used to test the current
(incomplete) parse_string implementation on LPC source files. Note that
the grammar does not handle floating point values.
The value returned is an array of token values; any structure in the
grammar is currently ignored. The maximum number of tokens the function
can currently handle is 10000, so use it with small source files only.
