a hackerish solution is
fp: copy []
text: "This is text"
insert tail fp rejoin["" <tag> text </tag>]
but that should only be used till a correct solution is given
join assumes the resulting type is the same as the first type.
when the first type is a tag! it tries to make the whole block a tag
... badly
by putting an empty string first, join just builds a string
