Velocity - dynamicaly populating ArrayList

Having:

#set( $maxVersion = 500 )

I'd like to populate list like this:

$myList = ("someString_10" "someString_20" "someString_30" ... "someString_500")

Any chance to populate it dynamically using velocity template only?

I've seen in the official docs, there is a support for the lists as well as for the #foreach loop. However it doesn't help here, I'd need kind of for/while specifying the condition to end the loop.

#set ($maxVersions = 500)
#set ($step = 10)
#set ($start = 1)
#set ($count = $maxVersions / $step)
#set ($myList = [])
#foreach ($i in [$start..$count])
  #set ($item = $i * $step)
  #set ($discard = $myList.add("someString_${item}"))
#end

$myList
