TypeError when sorting LooseVersions

[jwodder]

Using looseversion 1.0.1 on Python 3.10.6, the following occurs:

>>> from looseversion import LooseVersion
>>> versions = ['0.3.1@v0.3.1', '0.3@v0.3', '0.2.2.2@v0.2.2.2', '0.2.2.1@v0.2.2.1', '0.2.2@v0.2.2', '0.2.1.1-2@v0.2.1.1-2', '0.2.1.1-1@v0.2.1.1-1', '0.2-1@v0.2-1']
>>> versions.sort(key=LooseVersion)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/var/folders/l7/wrkq93d133d8zpn36fmqrq0r0000gn/T/pip-run-mkmcq5k0/looseversion.py", line 135, in __lt__
    c = self._cmp(other)

    if self.version < other.version:
TypeError: '<' not supported between instances of 'str' and 'int'

Also true of distutils.version.LooseVersion:

In [1]: from distutils.version import LooseVersion

In [2]: versions = ['0.3.1@v0.3.1', '0.3@v0.3', '0.2.2.2@v0.2.2.2', '0.2.2.1@v0.2.2.1', '0.2.2@v0.2.
   ...: 2', '0.2.1.1-2@v0.2.1.1-2', '0.2.1.1-1@v0.2.1.1-1', '0.2-1@v0.2-1']

In [3]: versions.sort(key=LooseVersion)

--> 352 if self.version < other.version:
    353     return -1
    354 if self.version > other.version:

TypeError: '<' not supported between instances of 'str' and 'int'

Here's what's happening:

In [16]: LooseVersion(versions[0]).version
Out[16]: [0, 3, 1, '@', 'v', 0, 3, 1]

In [17]: LooseVersion(versions[1]).version
Out[17]: [0, 3, '@', 'v', 0, 3]

I'm assuming you don't want to strip the @*, but this does seem like a use-case LooseVersion was not designed for, and these versions are redundant.

If there's something actionable here, please reopen.

This should be resolved in 1.2.0.
