1.5 Syntax, identifiers and names
The CFEngine 3 language has a few simple rules:
CFEngine built-in words, and identifiers of your choosing (the names
of variables, bundles, body templates and classes) may only contain
the usual alphanumeric and underscore characters (‘a-zA-Z0-9_’).
All other `literal' data must be quoted.
...
CFEngine uses many `constraint expressions' as part of the body of a
promise. These take the form: left-hand-side (CFEngine word) ‘=>’
right-hand-side (user defined data). This can take several forms:
cfengine_word => user_defined_template(parameters)
user_defined_template
builtin_function()
"quoted literal scalar"
{ list }
As you can see from the preceeding paragraph, scalar values are
quoted, lists are not.

That's right.

Per the reference manual, as quoted above, mentions of lists are not quoted.
I am sorry your documentation bugs have not been acknowledged yet,
bugs in the documentation can really frustrate new users and barrier
adoption.
