No. :-) I'm intending to mark the template delimiters ONLY in pairs
from now on. This is due to difficulties with the current approach,
which is to mark an opening < when it looks like a template opener.
It is rarely (?never) necessary to look very far for a matching >, since
a <..> pair can never enclose a ;, {, or } [*]. The "never" might happen
when you type a < shortly before an infinite number of #define lines.
But C++ hackers don't really use #define, do they? ;-)
[*] Any rough estimate of how large the gap between < and > gets in real
C++ programs would be welcome.
