IsErr can be used to compare an error to a target and also works when used on errors that haven't been wrapped since it will fall back to a string comparison.

IsVersion returns whether str is a valid release version with no -rc component.

VersionCmp returns an int indicating the difference between a and b.

WrapErr can be used to defer wrapping an error which is then decorated with the provided function name.
