Steps to reproduce
Note:
I've observed the symptom in the context of tab-completion in Visual Studio Code, but I assume the underlying problem is relevant to this repo.
The editor's tab completion / IntelliSense always "knows" the following phantom variables due to a leaky implementation detail (they correspond to the parameter names of the TabExpansion2 function):
$ast, $tokens, $positionOfCursor, $options
Tab-completion / IntelliSense results of these variables is based on the type these (parameter) variables have in Tabexpansion2, even if you explicitly define them with a value of a different type.
For instance, even if you define [int] $positionOfCursor = 42 in your script, tab-completion on a later line still shows the properties of the [IScriptPosition] type that the -positionOfCursor parameter is typed as.
Even if you don't define your own versions of these variables, their mere (ostensible) presence during tab-completion is confusing.
In an empty .ps1 file open in Visual Studio Code, type the following
$tokens.
Expected behavior
No IntelliSense results, given that $tokens isn't defined.
Actual behavior
IntelliSense results are the [array] type's instance property names, because the -token parameter of TabExpansion2 happens to be array-typed (Token[]])
