Not sure why Gamasutra blogs only get the little blurb without a “click to read” link or anything, but, well, click to read.
Or click this one
So {-my:x} lets you make I6 locals? That would be handy! Is it documented somewhere? I didn’t read about it in the change log, but I didn’t read the whole manual again either.
In Glulx Entry Points I had to add a local variable in one of the rules so that an I6 loop in the rule would have a variable to use. But the update changed the generated local names so that it stopped working. If this does what it sounds like it would be much safer, because the I6 phrase can then be safely included in any function.
The old {-require-ctvs} and the new {-my:x} are undocumented, which is why one turned into the other without warning.
