Errors while parsing double assignments

[displague]

stderr yields errors when parsing

<cfset x = y = 0>

I needed to see that in the official documentation. its there. yikes!

Even worse:
<cfset var x = var y = 0>
is valid.

That's some weird language design.
We'll see what we can do to accommodate it. it introduces a whole layer of parsing complexity that just shouldn't be necessary.... :-)

I had never seen that before. That is kind of yucky. Is that through the Jericho parser or Antlr?

It's going to have to be an Antlr solution. The whole expression inside gets parsed as a whole expression with the Antlr portion of the parser.
