Did I miss some steps? But I don't think this should be a problem in merging this PR.

[cristianoc]

This should go in the native section.

[wontheone1]

@cristianoc Could you elaborate a little bit? (what do you mean by this? and why should it go to the native section)

I found where pipe-first is documented in this repo and added the corresponding changes for pipe-last.

[wontheone1]

Reflected comments, or asked questions for the comments that I couldn't solve.

[wontheone1]

Please review again, changed as suggested.

[wontheone1]

@yawaramin @ryyppy Let me know if there is still changes to be done :)

[wontheone1]

All comments addressed. This PR is ready to review again.

[ryyppy]
