[Bug-apl] Reshape operator with variable on left-hand side doesn't work

[Elias Mårtenson]

When I use the ⍴ operator where one of the entries in the left-hand list is a variable, I get a DOMAIN ERROR:

The following works:

      2 1 ⍴ 10 11

10

11

But the following gives a DOMAIN ERROR:

      x←2

      x 1 ⍴ 10 11

DOMAIN ERROR

      x 1⍴10 11

      ^  ^

This happens even if the variable reference is itself stored in a variable:

      value←2   ⍝ 'value' is now assigned the value 2

      x←2 1     ⍝ x contains the list (2 1)

      y←value 1 ⍝ y should be the same as x

      x         ⍝ Let's confirm x's contents

2 1

      y         ⍝ y seems to be the same as x here

2 1

      x ⍴ 2 1   ⍝ Reshape with x works correctly

2

1

      y ⍴ 2 1   ⍝ But reshaping with y doesn't

DOMAIN ERROR

      y⍴2 1

      ^^

Is this a bug? I can't see what I could have done wrong here.
