------------------------------+---------------------------------------------
Currently, ghc-pkg list will print something like the following when no
package matches a query:
{{{
$ ghc-pkg list blargle
/usr/local/lib/ghc-7.4.1/package.conf.d
}}}
This is a deceptive answer for newcomers, because they assume that this
means the package was successfully found, and lives in
/usr/local/lib/ghc-7.4.1/package.conf.d. It would be nice if the message
explicitly mentioned that the result list was actually empty; for example:
{{{
$ ghc-pkg list blargle
/usr/local/lib/ghc-7.4.1/package.conf.d
(no matching packages found in this database)
}}}
