Hi Gavin, thanks for all the valuable feedback and this late of a
I've since fixed the issues that were brought up (notably the
Could you please restate/elaborate on where do you see inconsistencies
in the design (or perhaps the idea itself)?
The problem of making auto 'less nice' is I suspect not 'fully
solveable' but it is to a 'significant' degree (e.g. by the use of the,
existing, operator* or some possible use of operator | as is done by the
Boost.Range library with its adaptors)...
ps. OT/'to whom it may concern': fixing the 'too strong assertions'
problem (allowing multiple fallible_results to exist) and making it work
on Android (where we still don't have even proper 'POD thread locals')
with Clang forced me to reinvent boost::thread_specific_ptr (to avoid a
dependency on Boost.Thread) in the process of which I found that
Boost.Thread only asserts/'verifies' that calls to pthread_key_create()
and pthread_setspecific() succeeded (which my fail with ENOMEM)...
