wsfull using "where"

[tavmem]

In k2.8, an attempt to find an element in a mixed list (using "where") results in a "type error":

$ rlwrap -n ./k

\ for help. \\ to exit.

  & 1 = ( 1; (); "a")
type error
& 1 = ( 1; (); "a")
    ^
>  

But in kona, the result is "wsfull error":

$ rlwrap -n ./k
kona      \ for help. \\ to exit.

  & 1 = ( 1; (); "a")
wsfull error
& 1 = ( 1; (); "a")
    ^

The title of this issue is a bit misleading, as the use of "where" is incidental and extraneous to the problem. As the error message shows, the "type error" (and the "wsfull") occurs at "equals" (before "where" is encountered).
