If the value returned by @to_liquid@ is inserted into the output, it will be further converted with @to_s@ <em>(actually this is done implicitly by Array#join - see lib/liquid/template.rb)</em>
When used in a chained expression like @foo.bar@ or @foo['bar']@, the object returned by @to_liquid@ must either:
When used in a chained expression like @foo.bar@ or @foo['bar']@, the result of @to_liquid@ on the left-hand subexpression must either:
* respond to @has_key?@ and @[]@ (i.e. duck-type like a Hash); or
* respond to @fetch@ and @[]@ with an Integer argument (i.e. duck-type like an Array); or
* respond to @size@ or @first@ or @last@
In each case the object returned must also respond to @to_liquid@ or be a Proc. In the latter case, it will only be called if the previous element in the chain also responds to @[]=@ - that is, if the value can be cached in the parent object.
In each case, the object returned after applying the right-hand subexpression must also respond to @to_liquid@ or be a Proc which returns an object that responds to @to_liquid@. In the latter case, it will only be called if the previous element in the chain also responds to @[]=@ - that is, if the value can be cached in the parent object.
