PowerShell namespace matching is strange when namespace contains square brackets

[CoenraadS]

Input:

function foo {
    [string[]]$thing 
}

I would expect:

[string[]] - Namespace

Another example is:

[OutputType([System.Collections.Generic.List[int]])] => [OutputType([System.Collections.Generic.List[int]

Here is a regex that matches equal []'s: \[([^[\]]|(?R))*\]

But I read at

prism/components/prism-powershell.js

Line 29 in 7035d4e

// Matches name spaces as well as casts, attribute decorators. Force starting with letter to avoid matching array indices

something about not matching array indices but couldn't find an example of when it should not match

Hi! Thanks for reporting. The example regexp you provide is not a feature supported by regexps in JS.

But we can surely add support for one level of nested brackets to fix this issue.

Could two levels be added to support attributes with generic lists, i.e. [OutputType([System.Collections.Generic.List[int]])]

Thanks for this great project
