(:=) is a good feature, but has really nothing to do with this, and
should be in some generic place like stdlib (or in clib itself).

Using lists to implement put and putmap for tuples is not really good,
because the whole idea of mutable vectors is to avoid copying them --
that is, to update them in various ways using only O(1) space.
Mapping to lists and back requires O(n) space.  I'd suggest adding
"dotuple", "dotuplewith", "dotuplewith3" to stdlib.q and using them for
tuple operations.
