Oh, I'll have to correct this! I've only seen eForth mentioned with Dr Ting's name all over. Thank you.

The metacompilation part is really nice. Did the self-modification section of the essay not convey that to you? Because that's what it was :s I'll have to revise it.

I really want this essay to be definitive, so even after 4 revisions there is still some way to go. All the comments have been extremely helpful to further reach that goal :)

You should also look at how cmForth's metacompilation worked. It's even more fiendish, but relied on cmForth's separate interpreter and compiler dictionaries, which apparently was annoying to use. https://dl.acm.org/doi/10.1145/382125.382916

I didn't notice anything in the article that made me think of metacompilation, but maybe I missed it and should re-read.

Added: you should also look at Bill Muench's version of eForth including its metacompiler. I'm not that big a fan of eForth for practical use (it's TOO minimal) but wow it is simple.

Dr. Ting did a lot of wonderful expository writing about different Forths, including eForth, but yes, the eForth Model is by Bill Muench.
