Îõ³h&D Safe-Inferred/1ÄÅ×Ürequire-callstack;The constructor for this type is intentionally not exportedrequire-callstack9If you're running into this class, then you need to add  to your function's signature, or discharge the constraint using .require-callstackThis constraint is similar to ‰ in that it's presence will capture a stack frame for the call site of the function. This helps to preserve callstack provenance, whichrequire-callstack Raise an  and incur a " constraint while you do so. Thisrequire-callstack Satisfy a Ç constraint for the given block. Can be used instead of propagating a  up the call graph.Usage: main ::  () main = do   do  "hello"  Note how main does not have a  or 6 constraint. This function eliminates them, so that ) can be called without compilation error.    0require-callstack-0.2.0.0-2aJJJuKOm9wFKlV9teY3DhRequireCallStackControl.Exception ErrorCallProvideCallStackRequireCallStackImplerrorRequireCallStackprovideCallStack&$fIP"provideCallStack"ProvideCallStackbaseGHC.Stack.Types HasCallStackghc-prim GHC.TypesIOGHC.Base$
