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 I���ll get used to it (and In my case I think it���s likely 2 or 3 different exceptions)
