Hello,
I have the following problem. I'd like to infer types of local bindings
using 'reify':
------------------------------------
testValue =
let
a = 10
in
$(do
VarI _ t _ _ <- reify 'a
lift (pprint t)
)
-------------------------------------
But this code prints only:
-------------------------------------
*Debug> testValue
"t_0"
-------------------------------------
Is this intended behavior? Are there any workarounds?
Things work fine if symbol is defined in another module.
I do realise that in general $(...) may add additional constraints on local
variables.
