If you are taking suggestions for the next Lua release, mine would is that
it would be nice to have more detailed compiler messages.
For example, considering assignment instead of a test:
a = 1
if a = 1 then foo end
gives
Error: Loading Module 'Script Document1': :2: `then' expected near `='
With some fonts, = looks a lot like ==. If the test is complex, finding a
buried = can get hairy. Would it be possible to flag that as looking like
the programmer intended to do a test and accidentally did an assignment?
Here's another one:
`=' expected near `ot'
is thrown by
ifn ot CMyClass then
OK, I know this is obvious, but this one sometimes gets tough if you have
the right combination of characters.
There are plenty more examples where a more sophisticated error message
would be a great help.
Thanks,
Michael
