The `new` reader macro must resolve its first argument at compile time.
That's why (new (symbol s)) doesn't work.

You can use record's positional constructor:
user> (defrecord R [a])
user.R
user> ((find-var (symbol "user/->R")) 5)
#user.R{:a 5}

Ah OK, I didn't realise I needed to get into Java interop.
For education - can you (or anyone) explain me as to why what I was trying
didn't work?
Thanks Ambrose.

Hi Colin,
If you must call the Java constructor, you need reflection.
user=> (defrecord B [c])
user.B
user=> (def s "user.B")
#'user/s
user=> (.newInstance (first (.getDeclaredConstructors (Class/forName s)))
(object-array [1]))
#user.B{:c 1}
Thanks,
Ambrose
