Passing a map literal to a macro call forbids altering the map in any way,
while maps bound to an actual parameter may be changed

Key: VELOCITY-684
URL: https://issues.apache.org/jira/browse/VELOCITY-684
Project: Velocity
Issue Type: Bug
Components: Engine
Affects Versions: 1.6.1
Reporter: Sergiu Dumitriu
For example, with the following macro:
#macro(changeMap $map)
Before: $map.someKey
#set($map.someKey = 'new value')
After: $map.someKey
#end
This call works as expected:
#set($actualMap = {'someKey' : 'old value'})
#changeMap($actualMap) => old value, then new value
But this one doesn't:
#changeMap({'someKey' : 'old value'}) => old value, then again old value
