[Puppet Users] removing matching line from file

I've been using the stdlib::file_line resource happily for a bit now, but

I have a class, which can be simplified as follows

class prop(propval)
{
file_line {conffile:
line=>"PROPERTY=propval"
}
}


However, I'm attempting to plan for the future, and it sounds rather
useful to have the ability to remove the property completely.
The app I'm configuring this for, expects to see NO "PROPERTY=" value, if
you want to disable this feature.

Unfortunately, I dont see a way to do it, without some ugly exec() calls.

In other words, what I'd LIKE to be able to do, is someting like

file_line{ conffile:
line=>"PROPERTY=",
match=> "^PROPERTY=.*",
ensure=>absent,
}

and then have file_line remove a line, if present, that matches
"PROPERTY=".

After all, it can do

replace "^PROPERTY=" with "PROPERTY=foo"

So surely there's some way to do

replace "^PROPERTY=" with "[empty]"

?
