Note that the same ambiguity exists in the <exception-handler> syntax

as <exception-handler> ends with a <statement> and the optional
<"ELSE" statement-list> part start with "ELSE". Sloppy language
design, I assume by Borland.
What exactly do you consider "sloppy" ?
The ambiguity in the syntax whether ELSE belong to <statement> or to <"ELSE"
statement-list>.
The fact that the semicolon before the else is optional ?
I don't see a semicolon in the formal syntax.
