Difficult to move gene locus?

[TheLostLambda]

As far as I understand, I'd need to get the position of a gene with position(), move that, then get the locus for that gene with locus(), then write a function that can rebuild that same (arbitrarily nested) locus type with the new position spliced in? I'd need to, myself, write the code for unwrapping complements, joins, etc, and building them back up identically (with only the positions changed)?

Is there an easier way to do this that I'm missing? Or is this something that could be added?

Ideally I'd just do something like gene.position = new_position, or even new_locus.position = new_position; locus!(gene, new_locus), but the immutability doesn't allow that currently and I'm not seeing another straightforward way?

I suppose it could be useful to have something along the lines of shift(locus, n) (and shift!(gene, n)) to shift the position by n nucleotides. Would that help?

[TheLostLambda]

I think that would be massively helpful! Let me know if you'd like me to put in a PR for something like that!

shift and shift! are now in v0.4.6.
