A safelist filter ("safe" for lists)

Description

Right now, there's no way for a template designer to indicate that each element in a variable that's a list is "safe" for autoescaping purposes. Using the safe filter would treat the list as a string. For example, as reasonable workaround to #9700 might be to be able to write

{{ some_list|safelist|join:", " }}

Might be worth adding this.

More generally, perhaps a map filter or tag? I can imagine

{% map safe over some_list as safe_list %}
{{safe_list|join:", "}}

covering more situations, especially if it's lazy.

No, I'm intentionally not going for anything map-like. Templates are not a programming language.

Resolution: → fixed
Status: new → closed

(In [9952]) Fixed #9701 -- Added a "safeseq" template filter.

This is like "safe", except it operates on the individual elements of a
sequence, rather than treating the whole argument as a string.
