First of all I don't think that strict is a very useful restriction in golf. For instance a useful trick is to use punctuation variables like $, because Perl parses $,for differently than $_for. But using $, is strict-compliant in letter even though it definitely is not in spirit!

That said the natural approach at 46 letters happens to be strict-compliant: 

sub g{
(sort{abs($a-$_[1])<=>abs$b-$_[1]}@{$_[0]})[0]
}
