Question: Interest in replacing build-grammar.js with a purely PowerShell solution?

Would there be any interest in replacing the build-grammar.js script (in tools) with a purely PowerShell based solution? I have created a script/function/class that provides the equivalent of 'fast-plist' using the .NET XML reader and a PowerShell script (using a class) to 'ConvertFrom-Plist'.

Two caveats.

1. For performance reasons, I used a class, due to the fact that the inner function is highly recursive. The class with static method improved performance in excess of 4:1. This limits to PowerShell 5.0+.
2. In order to as closely match the formatting of the existing JSON file output, PowerShell 6.0+ is required, and a -replace operation to replace the space indent with tabs.

@jrsconfitto, I've also included a sample for converting to CSON as well:

The link to the ConvertFrom-Plist function has been updated above.

I think this is a good idea. Eventually we should make all the scripts and tests in PowerShell/.NET so we're on one stack.

@msftrncs Thanks for the sample, I'm willing to go to a PowerShell build for language-powershell.
