Change aliases to new syntax in several files

[JackStouffer]

Modernization and clarity.

FYI, #1002.

Martin seems to be in favor of the new syntax.

The area I disagree with him on is the idea that people will just incrementally change the code to the new syntax. Sorry to be a cynic but if it hasn't happened after two years of pull requests it isn't going to happen.

Though I agree that it's better to do it once and be done with it.

LGTM and we really should start to deprecate the old syntax...
