Status update for PLT 4.x compatible release
I’m nearing a PLT 4.x compatible release of LeftParen. The new version has a lot of new stuff in it, which I’m excited to publish.
In the meantime, someone named “fjl” went ahead and made the current version of LeftParen work with 4.x. (fjl, could you email me so that I can coordinate the “unforking” of LP?) I actually haven’t tried this code yet, but it might be worth a look.
