There's a few points like that, where a simple space can make all the
difference. It's hard to learn to watch out for single spaces ;)

That would be consistent (it's a tricky thing to get exactly right, as
Fabien can tell you)
I suppose it would currently be:
ok,err = pcall ->
doSomething!
error "throw a wobbly"
doAnother!
if not ok
print "failed, dammit!", err

The closest MoonScript gets AFAIK to a solution is the 'using' clause
for functions:
http://moonscript.org/reference/#the_using_clause_controlling_destructive_assignment
It's a good example of a problem generated by local-as-default.
