Yes.

The namevar is the primary key of the resource type. You might want to
reference the instance for dependencies (like "require =>
Mydefine['val']), so it has to be unique.

For your description I gather this should look like so:
| define explode() {
| file {
| [ "/location1/${name}", "/location2/${name}" ]:
| ...
| }
| }
|
| explode{ [ "filea", "fileb", "subdir/filec"]: }
or so:
| file {
| regsubst($array, "^.*$", "${path1}/\0"):
| ...;
| regsubst($array, "^.*$", "${path2}/\0"):
| ...;
| }
Be aware that only very recent versions of regsubst can handle arrays as
first parameter. You should be able to replace the single regsubst.rb
file on your puppetmaster without troubles.
