Functions

It is possible to define your own functions in MSE script.
The syntax for this is very simple, code in curly braces defines a function:
> { code goes here }

To be able to refer to the function it is usually assigned to a variable:
> function := { code goes here }

Calling a function is done using parentheses:
> { code }()
> function()
this has the effect of evaluating the code inside the curly braces.

--Parameters--

When calling a function, parameters can be specified inside the parentheses of the function call:
> fun := { "xyz is {xyz}" }
> fun(xyz: "a parameter")  ==  "xyz is a parameter"
These assignments are ''only'' visible to the called function.
> xyz := "outside"
> fun(xyz: "a parameter")
> # xyz is still "outside"

The syntax for parameters is @name: value@.
Multiple parameters are separated by commas.

The special syntax @value@ (without a name) means that the variable @input@ is used:
> fun := { input + var2 }
> fun(var2: "yes", "no")  ==  "noyes"
