Hi,

tldr; if I have a (defrecord MyRecord) in ns a.b.c and I have a string 
"a.b.c.MyRecord" how I can invoke (a.b.c.MyRecord.) (or (new 
a.b.c.MyRecord)?

I thought this was going to be as simple as (defn cfn "a.b.c.MyRecord") 
((symbol cfn).) but that throws an ArityException: wrong number of args (0) 
passed to Symbol.  I 

I have a protocol with a number of implementations.  Each installation will 
have a single implementation and will chose one based on an environment 
variable.  At runtime I need to look at that environment variable which 
defines the fully qualified implementation of a protocol.  I then need to 
instantiate that record.

Architecturally equivalent to a simple plugin system.  I could alias them 
all but that requires knowing about all the implementations which is a 
no-go.

This is where I feel the pain of not having OSGi :).

Thanks all!
