You'll need (try raise Not_found with Not_found -> p "exc"); p "done";;

I'd guess the reason the precedence is such is to require as few parentheses as
possible.  Most uses of try or match are not in a sequence of expressions, while
many if-then-else expressions are.  Essentially, matching constructs and if
constructs are not analogous.   Examples with clear indentation:

	if true then
		p "yes"
		p "no";
	p "done"

	if true then
		p "yes"
	else (
		p "no";
		p "done"

	try raise Not_found with
		| Not_found ->
			p "exc";
			p "done"

	(try raise Not_found with
		| Not_found -> p "exec");
	p "done"
