I said 'VALUE' because that is what is in the text:
Evaluates EXPR and exits immediately with that value.
(This is extra confusing because the word "evaluates" implies that
EXPR could be more than a scalar value -- which it can be, but only if
you parenthesize it to avoid operator precedence issues)
One could say 'exit EXITCODE' or something, I suppose.
Short of rewriting perlfunc to use 'exit(EXPR)' or having an explicit
statement of how things are prototyped, I don't see any easy answers
to make documentation clearer. How about this ultra redundant form:
exit EXITCODE
exit( EXPR )
