Remark: MonadQuotation
class is part of the Init
package and loaded by default since it is used in the builtin command macro
.
Simplistic MonadQuotation that does not guarantee globally fresh names, that
is, between different runs of this or other MonadQuotation implementations.
It is only safe if the syntax quotations do not introduce bindings around
antiquotations, and if references to globals are prefixed with _root_.
(which is not allowed to refer to a local variable)
Unhygienic
can also be seen as a model implementation of MonadQuotation
(since it is completely hygienic as long as it is "run" only once and can
assume that there are no other implementations in use, as is the case for the
elaboration monads that carry their macro scope state through the entire
processing of a file). It uses the state monad to query and allocate the
next macro scope, and uses the reader monad to store the stack of scopes
corresponding to withFreshMacroScope
calls.
