Allow variables bound in 'try' to be used in 'of' clauses
The following program would not compile:
-module(foo).
baz() ->
try Bar = 42 of
_ -> Bar
after
ok
end.
The error message is "foo.erl:4: variable 'Bar' unsafe in 'try' (line 3)".
There is no reason for 'Bar' to be unsafe, because if the pattern
after `of` is reached, `Bar = 42` must have been successfully evaluated.
