The first part, ``A``, can be one of:
- a list of file-level or library functions (``using {f, g, h, L.t} for uint;``) -
only those functions will be attached to the type as member functions
- the name of a library (``using L for uint;``) -
all functions (both public and internal ones) of the library are attached to the type.
- A list of file-level or library functions (``using {f, g, h, L.t} for uint;``) -
only those functions will be attached to the type as member functions.
Note that private library functions can only be specified when ``using for`` is inside the library.
- The name of a library (``using L for uint;``) -
all non-private functions of the library are attached to the type.
At file level, the second part, ``B``, has to be an explicit type (without data location specifier).
Inside contracts, you can also use ``using L for *;``,
