[stringtemplate-interest] Question on index with an offset in a sub-template

[Terence Parr]

Hi Jiwon, I think here, to be general, you need to pass in a map or 2 lists: {"apple":9, "orange":30}

then 

<attrs:{a| <a> is <attrs.(a)>th item}; separator=", ">.

if attrs is hash. this is for v4. in v3, iteration was on values not keys.
