Here we collect a variety of helper functions that construct or analyse HsSyn. All these functions deal with generic HsSyn; functions which deal with the instantiated versions are located elsewhere:
Parameterised by Module ---------------- ------------- GhcPs/RdrName GHC.Parser.PostProcess GhcRn/Name GHC.Rename.* GhcTc/Id GHC.Tc.Zonk.Type
The mk*
functions attempt to construct a not-completely-useless SrcSpan
from their components, compared with the nl*
functions which
just attach noSrcSpan to everything.

Collecting binders
isUnliftedHsBind :: HsBind GhcTc -> Bool Source #
Should we treat this as an unlifted bind? This will be true for any bind that binds an unlifted variable, but we must be careful around AbsBinds. See Note [isUnliftedHsBind]. For usage information, see Note [Strict binds checks] is GHC.HsToCore.Binds.

class UnXRec p => CollectPass p where Source #
This class specifies how to collect variable identifiers from extension patterns in the given pass. Consumers of the GHC API that define their own passes should feel free to implement instances in order to make use of functions which depend on it.
In particular, Haddock already makes use of this, with an instance for its DocNameI
pass so that
it can reuse the code in GHC for collecting binders.
