I should have written "would be sorely tempted to use File::PATH_SEPARATOR".
The spec is clear that colons get encoded, but it could still use a
clarification
for the slow reader showing how Windows paths are mapped.

Related question: the spec is silent about case insensitive filesystems.
How are they to be handled?  Worth mentioning in the spec even
if all you say is "undefined" for now...?
