I do not see a reason, why not to use this
(except, that " should not be escaped, of cause).

"_" are allowed in Python names. They are treated in the same
way as a letter.
DTML restricts the use of "_":
A name must not *START* with an "_" (unless it is the special
name "_").
Inside name, you can use "_" freely.

That said, you can also use:
<dtml-in expr="findClassTitle(code=class_code)">

I agree with Manuel:
you cannot nest DTML.
And it is this nesting, that triggered his "RING: do not do that!"
Use:
<dtml-in expr="findClassTitle(code=class_code)">
I.e. you can simply use the name of the variable.
Manuel is right, too, that DTML allows much more characters
in names than Python does. If you have a name with a character
forbidden in Python names, such as e.g. a "-", then you
can use "_[name]" or "_.getitem(name)" (as Manuel said).
It is only, that "_" (unlike "-") is allowed in Python names.
