[stringtemplate-interest] ST# - question regarding special casingof IList

[Jeremy Gray]

Re: ICollection - correct, it is IList that adds access by index. Sorry
about the confusion on that. That said, I wasn't aware that ST# needed
access by index, or even to the count exposed by ICollection. Is there
something about ST# I'm not aware of?

Re: IEnumerable - correct, virtually all .net collections are
IEnumerable. My point was that there are classes out there that are
IEnumerable but not ICollection or IList, and since it would seem that
ST# doesn't need ICollection or IList, why restrict it so that it cannot
enumerate those objects that only implement IEnumerable.

ICollection doesn't allow access by index iirc.

Virtually all .NET collections (including ILists, IDictionaries etc) are
IEnumerable.
