```julia
anonymous = (x -> 2x)
callanonymous(a) = anonymous(a)

normal(x) = 2x
callnormal(a) = normal(a)

julia> @code_warntype callanonymous(1)
Body::Any
1 ─ %1 = Main.anonymous(a)::Any
└── return %1

julia> @code_warntype anonymous(1) # fine

julia> @code_warntype callnormal(1) # fine

julia> @code_warntype normal(1) # fine

```

when I try to call an anonymous function inside another function, warntype caused. However, directly calling the anonymous function has no warntype!  
is there any work around to avoid the warntype? thanks. 🙏
