%*% errors informatively

Code
  a %*% b
Condition
  Error in `a %*% b`:
  ! Incompatible dimensions: "3x4" vs "1x4"

Code
  a %*% c
Condition
  Error in `a %*% c`:
  ! Only two-dimensional <greta_array>s can be matrix-multiplied
  Dimensions for each are:
  `x`: "3x4"
  `y`: "2x2x2"

%*% works when one is a non-greta array

Code
  x %*% y
Output
       [,1]
  [1,]    3
  [2,]    3

Code
  x %*% as_data(y)
Message
  greta array <operation>

Output
       [,1]
  [1,]  ?  
  [2,]  ?

Code
  as_data(x) %*% y
Message

Code
  as_data(x) %*% as_data(y)
