On the topic of abbreviations, I really like what Powershell does with aliases. You can quickly look up the definition of an alias in the REPL via Get-Alias (which has its own alias gal). It is also tracked globally so you can not only determine what an alias is referring to, but also find the aliases for some root command! The latter is actually really useful when learning Powershell to figure out what abbreviations are already available for a common command with a long name.

Even outside of programming, being able to lookup what the abbreviation is for some term is also quite useful since it can help avoid creating new duplicate short names for things.

anyone know where list* comes from?
