[I'm changing the subject line-- I kept looking for this discussion in JIRA]
Great way of way of framing this, Christopher. Thinking about
#evaluate as a companion to #include and #parse makes me realize this
new proposed directive fits within the Velocity approach.
Another idea is to have an optional argument with a map that would
serve as a context.
#evaluate("hello from $name",{"name":"Will"})

No, the #evaluate directive is to be used as it the following example:
#set( $error = $i18n_tool.getMessage("ERROR123") )
#evaluate( $error )## reder by merging with context
It something like the #parse directive, but the content comes
from a string and not a file.
