> my @bla = @arr; tr/h//d for @bla;

already mentioned in the OP

> my @bla = map{ tr/h//d; $_ } @{\@arr};¹

that's a nice one! 8)

But maybe my (updated) alternative is easier to read (?):

my @bla = map{ tr/h//d; $_ } map {$_} @arr;

Cheers Rolf

UPDATE: ¹) as tye pointed out it should be @{ [@arr] }
