Yes, for that process alone. So you don't want that to happen! The
try/finally idiom should definitely be used in such a case.
Does this come up because the component in question isn't producing
content of type text/html? Perhaps the comments should only be
generated when that content type is currently in effect.
I've also had this issue in the following situation, in text/html
content-type:
<:spool somestuff:>
<:component whatever.comp:>
<:/spool:>
<:set somestuff `somestuff.strip()`:>
<:if `somestuff`:>
<:#:>etc.<:/#:>
In this case, I want to take some action contingent upon whether
"somestuff" is non-blank. But "nonblank" isn't a markup-aware
concept, so it will produce the wrong results if component comments
aren't turned off.
