Inconsistent results from the link() function

[folini]

I noticed a strange behavior in dataview:
Calling the function link(s) on a string s dataview will generate a regular HTML link. calling the same function link(a) on the array a generates a slightly more complex HTML where all the links are listed in a <ul>...</ul> HTML Tag.

The unexpected behavior comes when calling join(link(a)) on the array a. The result is an HTML without the tag <ul>...</ul>. The list of links is now s simple sequence of HTML links (<a href='...'> separated by commas. As if the external function (join()) is changing the behavior of the internal function (link()).

Is this behavior intentional (it's a feature) or it's a bug?

These are quirks of rendering, not of the functions.

• link(string) produces a Link object. Dataview renders this as a HTML link.
• link(array) just converts all elements inside the array to links, producing an array of links (Link[]). Dataview renders arrays as a HTML list of links.
• join(link(array)) takes the array of links from above, and joins them all into a single string result (join(link(["hello", "goodbye"])) = join([[Hello]], [[Goodbye]]) = "[[Hello]], [[Goodbye]]"). This is a string and not an array and so dataview renders it directly without a list.
