No worries, here's a few ideas:
1) a version that use a "locals" method:
:: matrix-contains? ( m n -- ? ) n m [ member? ] with any? ;
2) a version that uses an inner locals quotation (i changed their names so
you can see it "renames" what is on the stack for the purposes of figuring
out what you mean):
: matrix-contains? ( m n -- ? )
[| matrix number | number matrix [ member? ] with any? ; ] call ;
3) a version that uses fry quotations:
: matrix-contains? ( m n -- ? ) '[ _ swap member? ] any? ;
4) a version that just uses simple words (note the "swap" since you pass
the matrix and then the number to search for):
: matrix-contains? ( m n -- ? ) swap [ member? ] with any? ;
5) or this version that doesn't use swap:
: matrix-contains? ( m n -- ? ) [ swap member? ] curry any? ;
