Thanks Richard - indeed it was that VisualAge Smalltalk pattern that I was remembering and looking for in Pharo, and was a bit surprised it wasnât there - and hence thought thereâre was possibly a different way. I might propose we add this, if no-one else comes up with a better alternative. Handling both application and http exceptions is quite a common pattern - and you donât always want to do the same blanket thing. Tim Sent from my iPhone

VisualAge Smalltalk has, in addition to the standard #on:do:, #when:do:, ..., #when:do:#when:do:#when:do:#when:do:#when:do:, with the last four mapping to #whenOneOf:doMatching:, taking two arrays.
It's easy enough to add your own methods like on: exn1 do: act1 on: exn2 do: act2 "An imperfect emulation of VAST's #when:do:when:do:" ^[self on: exn1 do: act1] on: exn2 do: act2
on: exn1 do: act1 on: exn2 do: act2 on: exn3 do: act3 "An imperfect emulation of VAST's #when:do:when:do:when:do:" ^[[self on: exn1 do: act1] on: exn2 do: act2] on: exn3 do: act3 to BlockClosure. It won't be fast, but your code might be clearer.

Thanks, I guess that makes sense, although it somehow looks a bit ugly with the nested brackets.. but nothing else springs to mind so maybe Iâll get used to it (and In my case I think itâs likely 2 or 3 different exceptions)
