That's just ugly. I use perl -wlne'eval;print$@if$@' (which doesn't print out the result of the eval; if I wanted that, I might do perl -wlne'print eval//$@//""').

    Ugly? It's true that one doesn't automatically get a printout of the last expression evaluated (one has to ask for it with p or x or print, etc.), but getting readline/history, trace mode option, and the joy of x alone makes this well worth it, IMO.

    BTW, I'm not sure what you had intended with 

    perl -wlne'print eval//$@//""'

    but it bombs: 
    % perl -wlne 'print eval//$@//""'
Warning: Use of "eval" without parentheses is ambiguous at -e line 1.
Scalar found where operator expected at -e line 1, near "//$@"
        (Missing operator before $@?)
syntax error at -e line 1, near "//$@"
Search pattern not terminated at -e line 1.
