[REBOL] Re: a new switch-like flow-control function
From: maximo:meteorstudios at: 19-Dec-2003 12:10
sorry for being late, but note that this works, straight out of the box:
describe: func [x [integer!] y [integer!]] [
switch true compose [
(x = 1) ["X is one"]
(y = 1) ["Y is one"]
(x = 2) ["X is two"]
(y = 2) ["Y is two"]
(true) ["X and Y are too big!"]
]
]
notice that its as easy to use as pif (its also 10% faster, on my computer).
>> describe 1 1
== "X is one"
>> describe 2 1
== "Y is one"
>> describe 2 2
== "X is two"
>> describe 3 2
== "Y is two"
>> describe 3 3
== "X and Y are too big!"
