BEWARE!
ENSURE-PATHNAME uses PARSE-UNIX-NAMESTRING, not PARSE-NAMESTRING.
In this case, you want PARSE-NAMESTRING (possibly through PATHNAME).

(describe (uiop/pathname:ensure-pathname "home:lisp;asdf;"))

#P"home:lisp;asdf;" is a pathname, with the following components:
NAME = "home:lisp;asdf;"
VERSION = :NEWEST

(Also, most of the time that you use MERGE-PATHNAMES, you should probably
instead be using UIOP:MERGE-PATHNAMES* or UIOP:SUBPATHNAME.)

CLHS pathnames are strange and shaky. UIOP tries to paper over the issues,
making them notably less shaky and the price of being a bit stranger.
