12.5. Generic return type instantiation

The GENERIC_RETURN module provides the [generic_return] annotation that allows generic functions to automatically deduce their return type from the body. This simplifies writing generic utility functions by eliminating explicit return type specifications.

All functions and symbols are in “generic_return” module, use require to get access to it.

require daslib/generic_return

12.5.1. Call macros

generic_return::generic_return

Replaces generic_return(expr) with a block that calls expr and returns its result, handling void, copyable, and movable return types.
