Gaps in the grammar of Tritop

How explicit should it be when indicating spaces, is it or is it not allowed? For example, these rules:

rule lambda
  'lambda' ( '(' params ')' )? block
end

rule params
  # ...
end

rule block
  '{' # ... '}'
end

enough to match

lambda {
}

Basically, you need to specify wherever optional spaces may appear?

Yes Yes. In these rules, you need to skip spaces, but, for example, when analyzing strings that may contain spaces, you would like to keep them; what you should indicate.
