Why did you choose to use a recognizer? M[ ... pushes a matrix literal onto the matrix stack. MATRIX (or VECTOR) define a persistent matrix/vector value. M[ is not really parsing, it just sets a flag for the forth interpreter. You could write M[ 1 fdup ] instead of M[ 1 1 ] or M[ 1. 1. ] or M[ 1e 1e ] IOW M[ does not use a recognizer.
