How do you invoke a method (like a specific method, not a function)?

```julia
julia&gt; func(a) =5
func (generic function with 1 method)

julia&gt; meth = first(methods(func))
func(a) in Main at REPL[83]:1

julia&gt; meth(1)
ERROR: MethodError: objects of type Method are not callable
Stacktrace:
 [1] top-level scope
   @ REPL[85]:1
 [2] eval
   @ .\boot.jl:360 [inlined]

```

Right. Don’t rely on that working though, it’s not a public API
