Gleam and Erlang OTP: Typed Actor Framework vs. External gen_server Wrappers

Integration Boundary: Gleam Language and Erlang OTP
Gleam provides a native, typed actor framework via the gleam/otp library, which abstracts BEAM concurrency. Simultaneously, the language allows direct interoperability with Erlang's gen_server and other OTP behaviors through the @external attribute.
While the gleam/otp implementation offers compile-time safety for message passing, it does not cover the full surface area of the original Erlang OTP behaviors. Conversely, using @external to wrap Erlang libraries provides access to the complete OTP feature set but bypasses the Gleam type system, shifting the burden of type validation to runtime decoders.
When designing a system that requires complex supervision trees and state management, there is a trade-off between the safety of the typed actor model and the maturity of raw Erlang interop.
- How should a project balance the use of
gleam/otpactors against external Erlanggen_serverwrappers for advanced OTP behaviors? - What is the recommended strategy for validating dynamic data crossing the Erlang boundary to prevent runtime crashes caused by mismatched external type signatures?
