Is there a better way to run a command N times in bash?

Question

I occasionally run a bash command line like this:

n=0; while [[ $n -lt 10 ]]; do some_command; n=$((n+1)); done

To run some_command

For one, you can wrap it up in a function:

function manytimes {
    n=0
    times=$1
    shift
    while [[ $n -lt $times ]]; do
        $@
        n=$((n+1))
    done
}

Call it like:

$ manytimes 3 echo "test" | tr 'e' 'E'
tEst
tEst
tEst
