I've opened [https://github.com/mratsim/Arraymancer/issues/394](https://github.com/mratsim/Arraymancer/issues/394) in Arraymancer.
Those converters are private and were introduced to have less verbose code within Arraymancer. It's bad that they cause such issue so I will probably remove them. Plus I suspect that they contribute to my growing memory usage and time during compilation.
