You can also ->invoke by using parens()

Code

local( mylocal = 'My string' )

#mylocal()

Result

My string

Below is a simple counter type that overides the default ->invoke method.

Code

define mycounter => type {
    data public count = 1
    public invoke() => .'count'++ 
}

local( mylocal = mycounter )

#mylocal()
#mylocal()
#mylocal()

Result

123
