See #3040

I don't mind adding more template funcs, but we should have some kind of name spacing to make them easier to manage/document, i.e. strings.trimPrefix etc. Not sure how the "." works in this case, but then find something else ("_"?)

We should keep the "old" names as aliases, of course, but this will lead to more natural names like:

• image.config
• image.resize
• etc.
