[Ohrrpgce] assert that a particular piece of code has a script error?

[Ralph Versteegen]

There's no such feature. Its absence is certainly a nuisance for writing
test cases.
(hspeaktest.py can check for compile-time warnings and errors, but not
run-time ones)

I didn't have any ideas for a try/except block statement. I thought that
people wouldn't use it much since most wouldn't be familiar with
exceptions, and the additional complexity, didn't seem to justify it.
But maybe a more coarse-grained ability to specify a global (or per-script
or per-fibre) error handler would be useful. Either just for our purposes,
or as a public feature.
Incidentally, lua doesn't have try/except, but it has a special way to call
a function so that you catch errors inside it (pcall).
