Good point. Probably is allowed, I'll look at it today,
time permitting.

Approved.
I wonder if this is allowed:
function foo (a:t = x, b:u = (a = y, z))
i.e., I wonder what level of complexity is allowed in the
initializer expression, and if you potentially have to parenthesize
the expression when you output it?

Summary: Added support for initializers in SWF9
New Features:
Bugs Fixed: LPP-5308
Technical Reviewer: ptw (pending)
QA Reviewer: hminsky (pending)
Doc Reviewer: (pending)
Documentation:
Release Notes:
Details:
- Added grammar to recognize formal parameter initializers,
param = expression.
- initializers are checked to see that they are null (a current
restriction) if not, a warning is issued.
- For all runtimes but SWF9, the initializers are removed.
Eventually that behavior could change for all runtimes
(no removal of initializers) and with more work, we could
fully support them.
- changed the unparser to support printing the initializers
(not as pretty as it should be).
- removed some unused code in CodeGenerator, JavascriptGenerator.
Tests:
- smokecheck SWF8/DHMTL
- added test/optargs.lzx to test all cases, this is
now accepted by SWF8/DHTML. Gives reasonable results
in DHTML. I believe more work may be needed in SWF8
to support this.
- temporarily copied the functions from optargs.lzx to
LzNode to demonstrate it working for SWF9.
