#10082: implicit cpp_rational(double)

Comment (by marc.glisse@…):

 Argh, please don't base your design on dumb users. Using expression
 templates in the first place will cause problems for dumb users (and even
 not so dumb ones). And the 0.1 issue is in my opinion orthogonal to
 implicit/explicit. The example as you wrote it already compiles (it uses
 the explicit constructor), you want to write it:

 cpp_rational r = 0.1;

 if it is supposed to be an argument against making it implicit. But the
 "problem" won't really become worse by making the constructor implicit.
