Template arguments can be deduced from the type specified when taking
the address of an [overload set](over.over "12.3 Address of an overload set [over.over]")[.](#1.sentence-1)

If there is a target,
the function template's function type and the target type
are used as the types ofP andA,
and the deduction is done as
described in [[temp.deduct.type]](temp.deduct.type "13.10.3.6 Deducing template arguments from a type")[.](#1.sentence-2)

Otherwise, deduction is performed with empty sets of types P and A[.](#1.sentence-3)

A placeholder type ([[dcl.spec.auto]](dcl.spec.auto "9.2.9.7 Placeholder type specifiers")) in the return type of a
function template is a non-deduced context[.](#2.sentence-1)

If template argument
deduction succeeds for such a function, the return type is determined
from instantiation of the function body[.](#2.sentence-2)
