component with no inputs

May be it is a kind of strange question, but, did we say something
about the order of component evaluation ?

I just read

"The result of evaluating a pipeline is the result of evaluating the
steps that it contains, in the order determined by the connections
between them"

We have p:load and p:error that have no input
Since p:load has output, we can determine an order for evaluation (not
a total order)
But this is not true for p:error
does this mean that we can throw the error anywhen
so a clever implementation would throw it first
so it means that when you have an error step, it is useful to now that
no step at same level would be executed

Do I miss something ?
