It is far harder to remove an addition that is regretted in the light
of further experience, than to have patience.

Real world? I wonder what that could mean. What counts as success? Do
you mean number of users, or do you have other criteria? What "law of
association" - excuse my ignorance. "Critical mass" usually refers to
the conditions necessary for an explosion.

There are rather a lot of reasons why so many people speak English
(see "Empires of the Word" by Nicholas Ostler
) but I think they are irrelevant to Lua. English has always been
fragmented into lots of little sub-dialects; the phenomenon of a
standard English is fairly recent, and I doubt whether that has been
much of a factor in the uptake of the language. However programming
languages are very different from vernacular languages. The fact that we
use the same word "language" should not lead us to stretch a metaphor.

That depends on the uses you have in mind.

I do not follow the reasoning here. Syntactic sugar is, by definition,
redundant - it gains you no greater expressiveness. It may have other
qualities which could make it worthwhile - brevity, a redundancy useful
for catching errors, and so forth. But removing it cannot decrease a
language's expressiveness - convenience, maybe? I am not sure why
academics would be the only people interested. Why not those programmers
and software engineers who happen not to be academics as well?
