I agree. non required semicolons that should end statements don't help
in the AS3 grammar either (for solving ambiguities like this).

Quoting Gordon Smith <gosm...@adobe.com>:
There has always been an ambiguity in AS3 about [Foo] being
interpretable as either metadata or as property access. (This is one
reason we're changing the metadata syntax in AS4!) I don't remember
the rule in the old compiler, but I think Falcon's rule is that if
the [Foo] is the first nonwhitespace on a line then it is metadata,
and this seems reasonable to me so I don't particularly want to
change it.

Subject: [jira] [Commented] (FLEX-33320) Falcon doesn't allow
multiline member access

Michael Schmalle commented on FLEX-33320:
-----------------------------------------
Have to check ECMA script or the AS3 docs. If this stuff is allowed,
then this is a bug in the grammar of antlr or the BaseASParser. I
could see this as being a not so hard fix since to get into the
array access or member state there has to be a correct predicate
which would be foo. or foo[a]
If Gordon doesn't chime in, I will look at the implementation. This
is where it sucks we don't have unit tests for the ASParser!

Key: FLEX-33320
URL: https://issues.apache.org/jira/browse/FLEX-33320
Project: Apache Flex
Issue Type: Bug
Reporter: Chema Balsas
Labels: Falcon
Attachments: MultilineArrayAccess.as, MultilineObjectAccess.as
Falcon doesn't allow multiline member access.
Try to compile any of the attached examples. Both are supposed to
render a textfield in the screen with the text "A test text" in it.
Falcon fails to compile both with errors like:
Internal error: Unable to generate code for 'MetaTags'
/Users/jbalsas/Documents/dev/apache/flex/falcon/trunk/compiler/tests/M
ultilineObjectAccess.as:12
Warning: Metadata was not bound to a definition
["bar"];
