Use a Boolean value to select one of two items from a sequence. :
|
|
|
|
[A B] false select
|
|
------------------------
|
|
A
|
|
|
|
|
|
[A B] true select
|
|
-----------------------
|
|
B
|
|
|
|
The sequence can contain more than two items but not fewer. Currently
|
|
Python semantics are used to evaluate the \"truthiness\" of the Boolean
|
|
value (so empty string, zero, etc. are counted as false, etc.)
