[boost] Desired libraries - n-ary trees, hashing and arbitrary-precision ints

Hello all,

I just want to mention three libraries I have a need for which, I believe,
are not currently in Boost.  My purpose is to see if they are under
development and what alternatives I have in the meantime.

1.
A dictionary implemented in terms of a user-supplied hashing policy

2.
A generic n-ary tree library parameterized by a vertex's user-defined
satellite data; to be used in a generic state space search library I am
writing and in storing a parse tree for an expression interpreter.  Perhaps
BGL could be used here?????  Not sure of its appropriateness...

3.
The frequently-requested arbitrary precision integer library

Thanks,
Dave
