Jan-Pieter, To amplify your mention of "bident" I executed trace against Rob's solution as follows. Trace reports Bident thrice, as you suggest.
trace'/ (%:@:) i. 8' --------------- 6 Bident ----- %: @: %:@: --------------- 8 Paren ------ ( %:@: ) %:@: --------------- 6 Bident ----- / %:@: /(%:@:) --------------- 6 Bident ----- /(%:@:) i. |syntax error: executet | t_z=. (/(%:@:))(i.)
