Glas doesn't care about keywords actually, the only "keywords" are the syntactic elements like ~ -> ->> { [ {{ {> <}

so you write:

    if: something ~ happened: and: something else ~ happened:
        logic ~ did: something ~ happened # ?

and

    for: x in: range: 12, 32
        {{ x }}

this chains the needed things nicely in fact you can write like this:

    in: range: 5, 13
        perform: a task

    for: x in: iter: person
        {{ x }}
