 Determine whether the given generic function has a method matching the given
 `Tuple` of argument types with the upper bound of world age given by `world`.
 
+If a tuple of keyword argument names `kwnames` is provided, this also checks
+whether the method of `f` matching `t` has the given keyword argument names.
+If the matching method accepts a variable number of keyword arguments, e.g.
+with `kwargs...`, the method's keyword arguments must be a subset of the
+provided names. Otherwise the provided names must be a subset of the method's
+keyword arguments.
+
 See also [`applicable`](@ref).
 
+!!! compat "Julia 1.2"
+    Providing keyword argument names requires Julia 1.2 or later.
+
 # Examples
 ```jldoctest
 julia> hasmethod(length, Tuple{Array})
 true
+
+julia> hasmethod(sum, Tuple{Function, Array}, (:dims,))
+true
+
+julia> hasmethod(sum, Tuple{Function, Array}, (:apples, :bananas))
+false
+
+julia> g(; xs...) = 4;
+
+julia> hasmethod(g, Tuple{}, (:a, :b, :c, :d))  # g accepts arbitrary kwargs
+true
