Re: [Jolie-devel] Jolie 1.2 - Inline trees

[Saverio G. <sav...@gm...>]

If I may toss an idea, what about making the syntax of inline trees as
close al possible to that of type declaration?

E.g., we have type

type myType: string {
.x[ 1, * ]: int
.y[ 1, 3 ]: void {
.value*: double
.comment: string
}
}

and we write

myTree << "Root" {
.x[0]=1
.x[1]=2
.y << {
.value[0]=1.1
.value[1]=2.1
.value[2]=3.1
.comment = "This is a comment"
}
}

Granted a comma does not make such a big difference, as an user I would
wander why one syntax needs the comma and the other does not.

BTW, should the deep-copy operator work inside inline trees or shall we
allow only assignments?

Best,
sg
