Byron Foster commented on VELOCITY-623:
---------------------------------------

I'm going to close this because it's related to the 2.0 issue of escape syntax, which is better discussed in an issue that deals with the problem in general.  And yea, this should work for both macros and references.

> provides another property 'runtime.references.strict.escape' that when true modifies the behavior of escaping a reference when in strict mode, see discussion VELOCITY-618.  The behavior is a as follows:
> $abc = <exception>    -  If $abc is not defined
> \$abc = $abc 
> \\$abc = <exception>  - If $abc is  not defined
> \\\$abc = \$abc
> The backslash in front of a reference always prevents that reference from being evaluated, and the backslash is removed. This is true wether a reference is in the context or not.
