The Pash grammar

[Jonathan]

I am asking for external help on the grammar for Pash.

So this basically our PowerShell grammar. This was not written by me,
but my mentor Igor:

http://pash.wiki.sourceforge.net/PashParserRules

Really it's quite good, but it's missing some functionality.

So we have some issues that neither I or Igor have been able to
resolve. The important [Object]::Method() and [Object].Property type
rules is an example of something I'd like to get working without
introducing indeterminism to the grammar.

So we need a working grammar, and it's a place we are stuck at. So
again I ask if we can get some help with it.
