($)(f::Function, args...)

Partially apply the given arguments to f. Typically used as infix f $ args

The returned function is of type PartialFunctions.PartialFunction{typeof(f), typeof(args)}

Examples

julia> using PartialFunctions

julia> simonsays = println $ "Simon says: "
println("Simon says: ", ...)

julia> simonsays("Partial function application is cool!")
Simon says: Partial function application is cool!

julia> typeof(simonsays)
PartialFunctions.PartialFunction{typeof(println),Tuple{String}}

<|(f, args)

Applies a function to the succeeding argument or tuple of arguments. Acts as the reverse of |>, and is especially useful when combined with partial functions for an alternative, low-parenthese function chaining syntax

Examples

julia> using PartialFunctions

julia> isdigit <| '1'
true

julia> (+) <| (2, 3)...
5

julia> map $ Int <| [1.0, 2.0, 3.0]
3-element Array{Int64,1}:
 1
 2
 3
