Ex. 01 Task 1: Parentheses for multiple >> operations

[labataschö]

Hi,

if we encounter an intermediate step like

Code: Alles auswählen

Lin(Foo, Lin(Bar) >> Lin(FooBar) >> Lin(BarFoo))

is it okay to omit the parentheses (like in the slides)? Or do we need to write

Code: Alles auswählen

Lin(Foo, Lin(Bar) >> (Lin(FooBar) >> Lin(BarFoo)))

instead?

Greetings,

Hi,

in our DSL, the >> operator is modeled using a class, and you only can use it in a prefix way, i.e.:

Code: Alles auswählen

Lin(Bar) >> Lin(FooBar)

is written as:

Code: Alles auswählen

>>(Lin(Bar),Lin(FooBar)) 

As a consequence, you cannot omit the parentheses.

Best,
Patrick
