What occured to me now, though maybe a mad idea and much more work, is
overloading as ..._value (..., bool& err) (somehow avoiding to have
the same signature as the existing functions), and for this variant
not to throw, but to set 'err' to true. This wholly avoids the
try/catch, leaves the user the resposibility to check 'err', but only
in the cases where he explicitely requested it by using this
overloaded variant.
