Personally I’d rather you declare force majeure on wait for HTML5 and
apply your considerable talents to implementing non-blocking versions
of everything. Wait et al causes issues all over the place, is usually
the least efficient way of doing things and the end result is almost
always a poor user experience. Given the choice of a little bit of
extra coding work implementing callbacks but with the side benefit
that users won’t be sitting there wondering what’s going on and an
engine that’s either 22x faster or half the size (both of which are
critical issues for HTML5) what do you think people would choose?

That actually is referring to *blocking wait* which is evil.
Non-blocking wait is entirely natural though. It is the difference
between being able to write code like:
on processThing
put url "..." into tInput
put revdb_query(..., "SELECT * FROM x WHERE y = %1", "tInput") into
tQuery
doThingWithQueryResult line 1 of tQuery
end processThing
And (imagining the existence of certain things):
on processThing
load url "..." with "processThing2"
end processThing
on processThing2 pUrlData
revb_query_async("processThing3", ..., "SELECT * FROM x WHERE y = %1",
"tInput")
end processThing2
on processThing3 pQueryData
doThingWithQueryResult line 1 of pQueryData
end processThing3
Of course, the point you raise a good one - make sure you can everything
non-blocking first then try and make non-blocking wait work. At least
that way round some things become possible in the HTML5 engine, even if
you have to rewrite some code to make it so.
Warmest Regards,
Mark.
