Starting to de-glob std

[mikedilger]

This #11983 looked idle. Could someone check if I'm going about this in the right way? @brson @alexcrichton

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @huonw (or someone else) soon.

I should probably put spaces after the commas.

Is it ok to still be referencing prelude (as in this pull request), or should I use from where things are defined?

[alexcrichton]

Thanks for taking a look at this @mikedilger! I think though that the issue is quite old at this point, and it's possible that we're going to have globs as part of the language proper for 1.0 rather than removing them.

It does seem that the readability of the imports decreases with this sort of rewrite to not use globs, so we may want to hold off on this for now. Would you be ok with that?

[mikedilger]

Yes thanks @alexcrichton for stopping me before I went too far.
