"Function Overloading", by thechange

Blitz supports a simple version of function overloading.

Code

;-------------------------------------------------------------------------------
; You can overlap all of Blitz' existing functions
; with your own function *and* variable names.

Function Text ( msg$ , x , y )
        Locate x , y
        Write msg
    End Function

; So basically you can rewrite any command not being a keyword/reserved word.

Const Plot = 0
    Const Line = 1
    Const Rect = 2
    Const Oval = 3

; If you use the same name for variables,
; they can coexist with the functions,
; even though their color coding is different in the IDE.

Graphics = Line

Select Graphics
        Case Plot
        Case Line
        Case Rect
        Case Oval
    End Select

; Actually this is just like being able to have
; the exact same name for your own
; functions, variables and even types and fields.

Type Struct
        Field Struct.Struct
    End Type

Global Struct.Struct

Function Struct.Struct ( Struct.Struct )
        Local Head.Struct

Head = New Struct
        Head\Struct = Struct

Return Head
    End Function

; Be careful ;)
