Multiple "params" in Snakemake file

I've got the following Snakemake file:

rule test:
    params:
        a = "a"
    shell:
        "echo {params.a}"

Which works as expected:

$ snakemake

a

But when I add a second parameter, I get an error:

rule test:
    params:
        a = "a"
        b = 5
    shell:
        "echo {params.a} {params.b}"

SyntaxError in line 4 of /home/mschu/Code/snakemake/Snakefile: invalid syntax

Why is that?

The documentation also has only examples with only one item in params.

Separate them by a comma:

rule test:
    params:
        a = "a",
        b = 5
    shell:
        "echo {params.a} {params.b}"
