Actually, you were right to say you can force a 2 component tuple
Gerard, as while this doesn't work...
>> t: to-tuple 1.1
** Script Error: Invalid argument: 1.1
** Where: to-tuple
** Near: to tuple! :value
this does...
>> t: to-tuple "1.1"
== 1.1.0
and despite the third number displayed there, it is a two component
tuple...
>> length? t
== 2
>> t/1
== 1
>> t/2
== 1
>> t/3
== none
As you say - test first - and keep testing till you get the answer you
want. ;)
