Those tests were broken with older versions of Boost that we don't test
against anymore. Furthermore, since we document that Boost and standalone
Hana installations should not be mixed, there's no risk of this change
breaking any existing code (that would be mixing standalone Hana with an
old version of Boost).
- Adds index_if
- Rewrites detail::index_if to use recursive alias stuff
optimized for tuple and basic_tuple
- find_if now uses index_if for Iterables
- at_key now uses index_if for Sequence
- Removes duplicate code and unnecessary special case implementations
- detail::advance_until
- at_key::advance_until
- tuple_tag implementation of find_if
- Uses Foldable instead of Sequence for cases where length is known.
(find_if had a specialization when Iterable and not Sequence)
- Adds test.*.auto.index_if for Sequences
- Adds test support/counter for testing infinite iterables
Also, add automatic unit tests for any_of, all_of and none_of. This commit
also makes it easier to add new automatic unit tests by documenting a small
shell script.
