over time, we got quite a jungle with all those
shome-me-the-type-of helper functions.
Reduced and unified all those into
- typeString : a human readable, slightly simplified full type
- typeSymbol : a single word identifier, extracted lexically from the type
note: this changeset causes a lot of tests to break,
since we're using unmangeled type-IDs pretty much everywhere now.
Beore fixing those, I'll have to implement a better simplification
scheme for the "human readable" type names....
...based on all the clean-up and reorganisation done thus far,
we're now able to rebuild the util::str in a more direct and
sane way, and thus to disentangle the header inclusion problem.
the usual drill...
only when wrapped into a factory function, RAII is really
airtight, even when used from within expression evaluation.
Thanks C++11 we're now able to provide such en passant
our lib::P smart-pointer is built on top of std::shared_ptr,
while additionally delegating comparisons to the pointee.
In a similar vein, I've now added a custom string conversion,
delegating to the pointee, with a type-string as fallback.
Together with the built-in string conversion for output streams,
we should now be able to remove most of the explicit string
conversions and calls to util::str in all of our test code.
This removes the last roadblock towards disentangling the
pretty-printing header includes, which in turn should allow
us to remove any conditional code in the built-in string
conversion of GenNode, Variant and the like. Which basically
was the objective for ticket #985
