64fb0ac Declare single-argument (non-converting) constructors "explicit" (practicalswift)
Pull request description:
Declare single-argument (non-converting) constructors `explicit`.
In order to avoid unintended implicit conversions.
For a more thorough discussion, see ["C.46: By default, declare single-argument constructors explicit"](http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#c46-by-default-declare-single-argument-constructors-explicit) in the C++ Core Guidelines (Stroustrup & Sutter).
