> An idea is to source code generate a single class with switch statements for from -> to, so we avoid adding them into the TC registry via DoubleMap which takes up heap memory and also the lookup requires to build a hash key.
> If we source code generate a single class with a single method that does a switch on the from, and then another switch per to that it supports, and then invoke the coverter, then there is no map registration needed and we can save heap memory, and the coverter is faster also.
> The JVM can much better optimize switch java code.
