valuerunReaderWithCompacted

:: Member (Embed IO) r
=> i
-> Sem (Reader i ': r) a
-> Sem r a

Run a Reader effect by compacting a value; otherwise behaves as normal. Useful for Reader effects which provide a large structure.

valuerunReaderWithExistingCompacted

:: Member (Embed IO) r
=> Compact i
-> Sem (Reader i ': r) a
-> Sem r a

Run a Reader effect with a value in a compact region. Will not add local values to the existing region, but will create a new region for it.
