I want to transliterate digits from 1 - 8 with 0 but not knowing the number at compile time. Since transliterations do not interpolate variables I'm doing this:

@trs = (sub{die},sub{${$_[0]} =~ tr/[0,1]/[1,0]/},sub{${$_[0]} =~ tr/[0,2]/[2,0]/},sub{${$_[0]} =~ tr/[0,3]/[3,0]/},sub{${$_[0]} =~ tr/[0,4]/[4,0]/},sub{${$_[0]} =~ tr/[0,5]/[5,0]/},sub{${$_[0]} =~ tr/[0,6]/[6,0]/},sub{${$_[0]} =~ tr/[0,7]/[7,0]/},sub{${$_[0]} =~ tr/[0,8]/[8,0]/});

and then index it like:

$trs[$character_to_transliterate](\$var_to_change);

I would appreciate if anyone can point me to a best looking solution.
