Bug: can't create a variable with the same name as a parameter

[dc42]

Running RRF 3.5.1+ in standalone mode. Given the following macro called testparam:

var G = null
if exists(param.L)
    set var.G = param.L
 
var L = 1
echo "testparam finished"

If it is invoked thus:

m98 p"/macros/testparam"

then it runs to completion; but if it is invoked like this:

m98 p"/macros/testparam" L100

it provokes the following message:

Error: in file macro line 5 column 8: meta command: variable 'L' already exists

Local variable and parameters should occupy distinct namespaces.

Fixed in 3.6-dev and back ported to 3.5-dev
