[Template-haskell] Splicing bindings

[Simon Peyton-Jones]

Sadly no.  Ideally one would like to be able to splice in *any*
syntactic construct, but at present implementing each requires separate
work in the implementation, and it's especially tricky if the construct
can bind things (such as declarations, patterns, and do-statements).  

Again, you can do it "by steam" using the lower-level constructors...
it's just more clumsy.

| Is there a way to splice in a
| 
|   nm <- m
| 
| binding?  I.e., I'd like something along the lines of
|  mdo
|   ...
|   $(defNm nm m)
|   ...
|   ... nm ...
|   ...
| 
| which would expand to
| 
|  mdo
|   ...
|   nm <- name "nm" m
|   ...
|   ... nm ...
|   ...
| 
| .  Is this possible?
| 
| 	thanks,
