04:08 idiosyncrat I'm at work on the Kollos symbol "mitosis".
04:09 idiosyncrat Kollos will use rewrites of the grammar much more than Marpa::R2 did, and the means the distinction between pre-rewrite symbols and rule, and post-rewrite symbols and rules becomes much more evident.
04:09 idiosyncrat I call the pre-rewrite rules and symbols XRLs and XSYs, and the post-rewrite rules and symbols IRLs and ISYs.
04:10 idiosyncrat In Marpa::R2 I could basically pretend XSY's and ISYs were the same things, and deal with the few situations where they weren't as special cases.  In Kollos that won't be possible.
04:11 idiosyncrat So the old Marpa::R2 symbols are undergoing "mitosis", dividing into XSY's and ISY's
04:13 idiosyncrat Currently, I'm going thru the test suite, making sure it deals properly with the distinction, and that it properly tests both XRL/XSY's and IRL/ISY's.
04:13 idiosyncrat 9 tests are converted; 31 remain
04:14 idiosyncrat The counts are misleading, because some tests are trivial to convert, and others will require some complex programming in the middle layers.
