Hi Maarten,
I've been checking the dollar and unescape code, still investigating.
I'm adding more tests.
Would something like
<set v="mvar" escape="true">this is my ${template}</set>
suit you ?
For now, this escape attribute is only implemented with the <print/> expression.
I'm looking into this, it's something important.
Best regards,
