maybeMissing =
path:
if !isPath path then
if isStringLike path then
throw ''lib.fileset.maybeMissing: Argument ("${toString path}") is a string-like value, but it should be a path instead.''

throw ''lib.fileset.maybeMissing: Argument is of type ${typeOf path}, but it should be a path instead.''
else if !pathExists path then
_emptyWithoutBase
else
_singleton path;
