hydra.overlay.python.util.lazy module
One-shot memoized thunk.
Mirrors hydra.util.Lazy from Hydra-Java. Holds a zero-argument callable; the
first get() evaluates it and caches the result, subsequent get() calls
return the cached value without re-evaluating.
Used by generated Python code wherever the kernel’s Haskell sources rely on
lazy let semantics: a binding’s value is constructed once even when it is
referenced multiple times, and is not evaluated at all when no use site is
forced. The Java head emits new Lazy<>(...); Python emits Lazy(...).
