Nathan Bubna commented on VELOCITY-618:
---------------------------------------

Yeah, i know very well how bad it is.  But it's been this way a long time and 
this upcoming release is still just a minor version one.   And yeah, i know 
about the \$alt problem.  This is why i essentially never use \ for escaping.  
It long ago became second nature to just use ${esc.d}alt (since i pretty much 
always have VelocityTools available).  Anyway, we can take the escaping 
discussion over to VELOCITY-623.

I'll try and get the rest of this strict mode stuff in shortly (sans the 
escaping part).

> The given patch against trunk adds a new option 'runtime.references.strict'.  
> When set to true, invalid property references will throw a 
> InvalidMethodException.  For example $foo.bar will throw an exception if the 
> object contained in $foo has no such property as bar.  Any kind of reference 
> to bar will cause an exception including:
> #if(#foo.bar)
> #set($foo.bar = "junk")
> #set($foo.getBar())
> etc...
