[BUG] Parameterised Transclsuon: Function Invoking in Filter Returns Different Results

[kookma]

Describe the bug

Function question

Aren't these the same, why they return different results?

\function f(date) [tag[Learning]]:filter[get[created]split[]first[4]join[]compare:number:gt<date>]

<$list filter="[function[f],[2018]]" >
<$link/> - <$text text={{{ [{!!created}split[]first[4]join[]] }}}/><br>
</$list>

<$list filter="[<f 2018>]" >
<$link/> - <$text text={{{ [{!!created}split[]first[4]join[]] }}}/><br>
</$list>

The last example only returns the first output!
@btheado: Can we conclude the second example is similar to what you said for <<myfun param>>? So even calling a function inside a filter expression using <> it returns the first output!

Yes, your second example uses the function as a variable so both scenarios are the same.

Thank you Saq! This is a little confusing and I would recommend clarifying this in the official docs.
I assume the PR for docs should target parameterised-transclusions branch. I will prepare some explanation on this.

[saqimtiaz]

@kookma docs updates for parametrised transclusions should target the master branch, since the PR has been merged.
