In general in Zope 3 it's my understanding that it's better to do
try:
c = IMenuItems(content)
except ComponentLookupError:
return ''
... c used as iterable ...
return ...
than testing directly for the provided interface, as it gives an
opportunity for an adapter to do its job. It's probably slower
though, and maybe not a pattern generally used for marker interfaces.
Opinions ?
