Aviem Zur updated BEAM-1337:
----------------------------
Description:
Today the user must explicitly provide any coders needed for serializing state
data. We'd rather use the coder registry and infer the coder.
Currently all factory methods in {{StateSpecs}} take a coder argument. For
example:
{code}
StateSpecs.value(coderForT);
{code}
We could leverage the coder registry and provide different overloads:
TypeDescriptor:
{code}
StateSpecs.value(typeDescriptorForT);
{code}
Reflection:
{code}
StateSpec.value();
{code}
