Consider the following functional as an example:

    ClearAll[urlModifier];
    urlModifier[url_]:=ReplaceAll[Function@Evaluate[
    	Inactive[URLBuild][
    		URLParse[url]/.{"slot"->Inactive[StringReplace][Slot[]," "->"_"]}
    	]
    ],{Inactive[x_]:>x}];

If I evaluate it using the following command:

    urlModifier["https://www.somewebsite.com/path/slot"]["hello world!"]

It fails probably because the `Slot[]` is not aligning with the `Function`.

But if I do in-place evaluation of `urlModifier["https://www.somewebsite.com/path/slot"]` and use the result as input:

    URLBuild[<|"Scheme"->"https","User"->None,"Domain"->"www.somewebsite.com","Port"->None,"Path"->{"","path",StringReplace[Slot[]," "->"_"]},"Query"->{},"Fragment"->None|>]&["hello world!"]

It works fine.

What should I do to `urlModifier` to make it accept the `Slot[]` for its `Function` that it creates?
