Any #commonlisp wizards out there?

I'm on a journey to explore the Common Lisp ecosystem and so far so good.

While figuring out which SQL/MySQL system to use, I stumbled across the testsuite for `cl-dbi` where it uses `:|some_string|` to retrieve the value from a result row.

I have run out of ideas on what to search for to find the meaning of `:|somestring|`.

`:a-keyword` is a keyword.
`|a-symbol` is a symbol.

@johanmynhardt one can ask Lisp about it. DESCRIBE prints a short description of a data object.

CL-USER > (describe :|I woke up early this morning.|)

:|I woke up early this morning.| is a KEYWORD
NAME "I woke up early this morning."
VALUE :|I woke up early this morning.|
FUNCTION #<unbound function>
PLIST NIL
PACKAGE #<The KEYWORD package, 0/4 internal, 7626/8192 external>

Thus it is a symbol in the KEYWORD package.
