Actually no-one was arguing it should go faster, merely that it should be
easier to type. There are two legitimate concerns as I see it:
1) when t is a long name. Could be particularly embarrassing if you misspell
it (personally I don't like long names, but hey)
The problem is not with the operation, but with the name of the
table. If it bothers you why don't you simply change it to a short one?
2) when t is a more complex expression, eg: f(x)[#? + 1] = value.
The problem here is not with the append operation also. It shouldn't
be clear/legible to separate the "more complex expression" into two small
and readable ones? Something like: local t=f(x); t[#t+1]=value
In both cases I think the discussion is diverging to a kind of
competition of tastes: "I prefer this" X "I prefer that" :-(
I'm always very loath to suggest or support more syntax, but how about if '#'
on its on in an expression inside  were to mean the length of the table
being indexed. So you could go:
t[#+1] = value
It's pretty clear, and almost syntactically unambiguous.
And one-character less (to use this subjective argument) than
the current (and I think unquestionably legible, clear, unambigous...):
t[#t+1] = value
