Documentation - factories - usage not shown

The section on factories shows two alternatives on how to define a factory:

def taxCalculator(taxBase: Double) = wire[TaxCalculator]
    // or: lazy val taxCalculator = (taxBase: Double) => wire[TaxCalculator]

It does not show though, how a class can depend on such factory.

This answer on SO shows, how to inject a factory defined in a val (or lazy val) - second line in the documentation snippet

However, I have found no way on how to inject a factory, which is defined using a def - first line in the documentation snippet.

Start with the factories section containing the taxCalculator def and lazy-val examples, then review the linked Stack Overflow answer for the existing val-based injection pattern. Verify whether a factory defined with def can be injected, and update the documentation to show the supported usage or explain the limitation.
