It would be an overkill to do it for this particular case, but Smalltalk makes it possible to implement a case-like construction:

[ expression��]��

��when: [ :value |��condition1 ] do: [-0do :value |��...��];��

��when:��[ :value��|��condition2 ] do: [ :value |��...��];��

��otherwiseDo: [ :value��|��...��];

�� evaluate

I am sure, something like this has been implemented already somewhere (maybe in Squeak?). Still not sure it is practical as compared to simple if-s, and for sure not widely used :)

...On the other hand, sometimes the case-like construction can be considered a more intension-revealing style.��

Hello,

Im trying to solve a challenge from exercism where�� I have to calculate the points somehow gets on a very simple darts board.

I solved it like this :

scoreX: anInteger y: anInteger2
�� | distance |
�� distance := (anInteger squared + anInteger2 squared) sqrt.
�� distance > 10
�� ifTrue: [ ^ 0 ].
�� distance > 5
�� ifTrue: [ ^ 1 ].
�� distance > 1
�� ifTrue: [ ^ 5 ].
�� ^ 10

but now I use three if then and I think it's ugly code.

Is there a way I can make it more the smalltalk way ?

Regards,

Roelof
