Hi Eric.
If I want to write a program that generates Poke output, it's easier
to generate [1,2,] than it is to generate [1,2] having to special-case
the last element. After all, C99 allows trailing commas in enums to
correct a shortcoming in C89's syntax.
* src/pkl-tab.y (array): Allow trailing comma in arrays.
* doc/poke.texi (Array Literals): Document it.
* testsuite/poke.pkl/arrays-9.pk: New file, to test it.
Nice addition. Pushed to master.
Thanks!
