Actually, I can think of examples from programming languages
which do permits just this sort of thing. The one which comes
most quickly to mind is from COBOL,
Read ... On Size-Error ...
or
Search ... At End ...
among others.
Even some variants of BASIC have an ON ERROR ... statement.
The virtues, if any, of the declare block are not limited to
exception handling. A simple,
begin
...
exception
...
end;
will accomplish that purpose. Though I prefer infrequent usage of
ad hoc constructs whether explict as "declare blocks" or implicit via
in-line declarations, I tend to believe that when such constructs are
appropriate, the declare block will provide greater service over the full
life-cycle of a deployed software product. While brevity may be the
soul of wit, clarity would seem to be the soul of understanding.
In the end, however, we each gravitate toward the idiom that feels
most comfortable. A great Rabbi is reported to have said
(paraphrasing), "For those who believe an idea to be true,
no proof is necessary. For those who do not, no proof is possible."
