See https://coveralls.io/builds/17797671/source?filename=ytypes%2Flist.go#L476 -- we have a number of error cases that we're not covering with existing tests. This issue tracks covering them.

Currently, it appears that the only way one can modify an alias is to remove it and re-add a new entry. It would be nice if while on the Modify screen for the parent hostname, if all aliases were also listed and options to modify / remove those aliases were available.

For normal builds, it is helpful to have more specific versions than simply the upcoming version snapshot. 2019.2.MMDD.HHmmSS.0 seems like a reasonable format. It combines the year major and minor open source versions with a timestamp and ending in .0 which follows an internal convention where these are treated specially as development builds.

It should be possible for the user to not use whitespace around the operators in the expr command. Right now, this is a syntax error:

$ ./netcalc.py expr 192.0.2.0/24 -192.0.2.0/25
usage: netcalc.py [-h] COMMAND ...
netcalc.py: error: unrecognized arguments: -192.0.2.0/25

This relates to the simple way in which we're parsing the command line. We'll need to be smarter than this.
