I think that at the end of the day, everything might depend on how the 
current internal implementation of the template engine is.
From an end user perspective


$this.is.a.stupid."name with $, .  and spaces"$ might actually be great and 
more generic than simply replacing spaces with _.
I think allowing spaces or special characters without quoting them might be 
unwise and this would bring us extremely close to allowing everything yaml 
supports.
