Re: [Bug-apl] jot dot jot dot?

I don't think that's true. Here's an example from IBM APL2 Workstation:

      (1 2)(3 4)∘.∘.*(5 6)(7 8)

SYNTAX ERROR

      (1 2)(3 4)∘.∘.*(5 6)(7 8)

      ^

      (1 2)(3 4)(∘.∘).*(5 6)(7 8)

SYNTAX ERROR

      (1 2)(3 4)(∘.∘).*(5 6)(7 8)

      ^

      (1 2)(3 4)∘.(∘.*)(5 6)(7 8)

  1  1         1   1     

 32 64       128 256     

                         

  243  729    2187  6561 

 1024 4096   16384 65536

It seems to me that APL2 parses it as 

°.(°.*) , in which case APL2 has some operators with a long left scope and others with a long right scope.
