[stringtemplate-interest] ST# - questionregardingspecialcasingofIList

[Jeremy Gray]

Re: "other issues e.g. with attributes of type Hashtable/IDictionary for
instance" - They too are special-cased, though at a higher level of
priority, so I'm not sure how that presents any more of an issue given
that they too already implement IList and it isn't a problem at the
moment.

Re: "Have you actually tried this with an ICollection?. And an IList." -
not as of yet, though I do recall reading a recent post on this mailing
list that stated that only item retrieval worked, not other properties.
If I've posted too quickly and in error from not having checked it
myself, I do apologize.

Re: "Template application is applicable to all attributes." - Yes, it
is, but has different semantics for those that are (at present) IList,
does it not?

I have to admit that unless I'm still missing something, the position on
using IList for multi-valued attributes instead of the most appropriate
interface, that being IEnumerable, is rather like hiding a pea (in that
anything that would count against IEnumerable already (and still would)
count against IList, except that targeting of IEnumerable would allow
multi-valued handling of objects that aren't IList)

By the way, at the end of the day I absolutely love ST#, so do bear in
mind that all this is just in the interest of curiosity and exploration.

Jeremy,

True. I could have but, that creates other issues e.g. with attributes
of
type Hashtable/IDictionary for instance.

IEnumerable

Have you actually tried this with an ICollection?. And an IList.

Template application is applicable to all attributes.
