a=. 3 : 'y+4' ; 3 : '2+3'
Where did the comma come from in the tree diagram for 'a' , and what does it
mean?
a=. 3 : 'y+4' ; 3 : '2+3'
a
3 : 'y+4' ; 3 : '2+3'
5!:4 <'a'
┌─ 3
┌─ : ─┴─ ,:'y+4'
├─ ;
──┤ ┌─ 3
└─ : ─┴─ ,:'2+3'
This has some interesting twists:
aa=. 13 : 'y+4' ; 13 : '2+3'
aa
(4 + ]) ; 5:
5!:4 <'aa'
┌─ 4
┌────┼─ +
│ └─ ]
──┼─ ;
└─ 5:

Not really a nested definition, but a sequential one. When the
interpreter sees x : 0, it drops what it's doing and reads lines from
the input. When it finds ), it resumes what it was doing.
