Notice that the tree produced by (string->tree "<gtr>") and
(string->tree ">") is not the same one. Save your file and look at it
in less (or more or emacs or ...). One is \>, the other \<gtr\>.

Try with (string->tree "<"). It gives an _invalid_ tree.

No. I want (foo "<gtr>") to be the tree that gets serialized as
\<less\>gtr\<gtr\> in a .tm file. This means the '<' symbol, followed
by the letters g, t and r and then the '>' symbol. Not the '>' symbol
alone.

Yes, exactly.

So you are saying that this function is _not_ part of TeXmacs?
