In the following document the second a is much nearer placed to the V:
\starttext $V \mathbin{a} W \qquad V \mathbin{\mathbin{a}} W $ \stoptext
(in the second case an italic kern seems to be missing)
Can one avoid this side effect of nested \math-command? When building symbols it is not always easy to avoid such nestings.
