Circular alias causes memory leak

[danielboothcloud]

I foolishly set up an alias for persistent volumes wrong.
I now have two aliases:

alias persistantvolumes = 'pv'
alias pv = 'persistantvolumes'

Essentially, whenever I try to type pv or persistentvolumes now, the terminal hangs until. Eventually, my system runs out of memory, and I am forced to quit the program.

This renders the persistentvolumes option inaccessible, as there appears to be no option to delete or remove aliases.

It would be cool if there were a feature that allowed the user to remove aliases.
