Woonsan Ko commented on LANG-893:
---------------------------------

':-' seems to be a good option as default delimiter. Also seems simpler and focusing more on string substitution than others. And, of course it should be customizable like prefix/suffix of StrSubstitutor. Thanks for the suggestion!

> I'd need a default value for a placeholder that cannot be resolved.
