Interesting. Given the following definition of pp:
∇Z←X pp Y
⎕←'comparing'
⎕←' X=' (8⎕CR X)
⎕←' Y=' (8⎕CR Y)
Z←X≡Y
∇
I get the following output:
*(⊂'foo') pp¨ (,⊂'foo')*
comparing
X= ┌─────┐
│┌→──┐│
││foo││
│└───┘│
└∊────┘
Y= ┌→────┐
│┌→──┐│
││foo││
│└───┘│
└∊────┘
Seems to be to be a bug in the implementation of ¨ (each).
