The type of .con print_int_matrix [mem: %mem.M, k: .Nat, l: .Nat, m: %matrix.Mat (2, (k,l), I32), return : .Cn [%mem.M]];
is rewritten to cc_print_int_matrix_3068959 : [%mem.M, [], .Nat, .Nat, %mem.Ptr («k_3068787; «l_3068793; .Idx 4294967296»», 0), .Cn %mem.M].

The dependency is lost resulting in error: cannot pass argument.

Note: Intermediate solution: Ignore dependencies in the type scheme by writing a wrapper that replaces (k,l) with (⊤:.Nat,⊤:.Nat) using bitcasts.

This is a known limitation. See also Typed Closure Conversion for the Calculus of Constructions.

Relabeling as enhancement.
