Control.Monad.Loc.TH
Description
The TH macro withLocTH to manually annotate program points,
but you should always use the preprocessor if possible.
Documentation
withLocTH is a convenient TH macro which expands to withLoc <source location>
It should only be used when the MonadLoc preprocessor is not available.
Usage:
f x = $withLocTH $ do
$withLocTH $ something
x < -$withLocTH $ something-else
...NOTE: unfortunately type signatures are necessary when using withLocTH
