[Zope-dev] ZPatterns: SkinScript semantics

[Steve Alexander]

In a SkinScript COMPUTE statement, should I be allowed to supply 
different names in the OTHERWISE LET section as in the attributes section?

For example:

WITH some_query() COMPUTE
   foo,bar,baz
OTHERWISE LET
   foo='There is no foo',
   spoon='There is no spoon'


Looking at the ZPatterns code, I don't think this attribute provider 
will get registered for providing "spoon", although "spoon" will get 
calculated if foo, bar or baz is requested.

On the other hand, you could consider the above as a shorthand for:

WITH some_query() COMPUTE
   foo,bar,baz,
   spoon=NOT_FOUND
OTHERWISE LET
   foo='There is no foo',
   spoon='There is no spoon'

In which case, it works entirely as expected.
