Yes, I agree.

| The only problem I can see would be if the pipeline engine wasn't able to infer
| that two or more steps used the same input before the second use occurred. That
| could happen if the engine didn't look at the entire pipeline definition ahead
| of starting the processing

Yes, implicit in my question was the requirement that pipelines
perform an analysis of the whole pipeline before starting.

| or if it couldn't be inferred from the pipeline
| definition that two steps actually used the same input.

I think for explicit p:input statements, that doesn't happen, though we
do have that issue with implicit inputs.

| I don't think either of
| these can occur with the current design, but I think we need to steer clear of
| dynamic inclusion of pipeline documents.

Absolutely.
