| Aug 9, 2013 at 2:57 | comment | added | Mr.Wizard | I just wanted to say that in the time since I doubted the value of this construct I have come to really see the value in it. Critical for me is the behavior that the function does not evaluate until the pattern matches. Please consider placing notice of this behavior conspicuously in your answer. I'd +1 a second time if I could. | |

+1 for the RightArrowBar thing, which makes this a lot more usable. You're now set up to collect a 100pt bounty. Congrats!

@Mr.Wizard And another thing, if you call something like f[_Integer]:=code;f[2.3] You get the unresolved "call". If you try to emulate this using your method, you get the unchanged input to the replacement, instead of getting the unresolved "call". To be specific 0.3/._Integer:>code yields 0.3, while dFunction[{_Integer},code][0.3] yields itself, meaning that your output specifies that you have the unresolved call, rather then just passing on the input to higher functions. Speedwice my best bet is that you win by a factor of 2 due to my version having two pattern checks.

| Aug 23, 2012 at 12:52 | comment | added | jVincent | @Mr.Wizard I didn't claim that it was superior in any way. It's a stylistic choice I sometimes find I have a short function which doesn't do much, so I replace it with an anonymous function, however if the function relies on pattern matching, as is often the case for my MapIndexed functions, I can't easily do this. But with this definition it's no problem. So really it's a style choice. I decided to post it since Mike also commented that it was a shame Function didn't support destructuring. | |

I usually like your answers (in fact I know through ♦ magic that I've upvoted your posts more than anyone else), so please don't take offense, but honestly how is that in any way superior to the forms that I show? It looks very clumsy to me compared to triDiagonalQ[mat_] := And @@ Flatten @ MapIndexed[#2 /. {i_, j_} :> # == 0 || Abs[i - j] <= 1 &, mat, {2}]
