templater: make _hybrid not callable to avoid conflicting semantics In templater, a callable symbol exists for lazy evaluation, which should have f(**mapping) signature. On the other hand, _hybrid.__call__(), which was introduced by 0b241d7a8c62, generates mapping for each element. This patch renames _hybrid.__call__() to _hybrid.itermaps() so that a _hybrid object can be a value of a mapping dict. {namespaces % "{namespace}: {names % "{name }"}\n"} ~~~~~ a _hybrid object
