Hi Alessandro,
I know a solution to making 'la work. Try...
view layout load la
But I'll leave it up to someone else to explain why 'load makes it
work. I assume it's something to do with "Binds words to global
context." as mentioned with 'load's help...
>> ? load
USAGE:
LOAD source /header /next /library /markup /all
DESCRIPTION:
Loads a file, URL, or string. Binds words to global context.
LOAD is a native value.
And don't worry - I scratched my head over the first time I saw 'load
used like this as well. (:
