I don't remember seeing any reference to this in the documentation for eval. If their were I would have used it.

Perhaps it should be there? It seems to me that eval {} or do {} is the perfect idiom for using eval with exceptions.

    perldoc -q eval
    In both forms (eval EXPR / eval BLOCK), the value returned is the value of the last expression evaluated inside the mini-program; a return statement may be also used, just as with subroutines. The expression providing the return value is evaluated in void, scalar, or list context, depending on the context of the eval itself. See "wantarray" for more on how the evaluation context can be determined.
