Hi all.
I'm trying to use a map with a tuple as the value. From the
documentation it looks like it would be possible. But I just can't get
it to work.
Look at this small example. When it tries to parse the value of the
map-entry it won't accept a tuple. Do I need to implement an own
loader??
grunt> cat mapwithtuple;
[words#(word1,word2),title#anicetitle]
grunt> x = load 'mapwithtuple' as (m:map[]);
grunt> dump x;
