So it is the last untyped **actions** parameter which is causing the problem?
**Changing the top example:**
var lastGreeting: string
template greet*(lastGreeting: untyped, text = "Hello", who = "Bob",
actions: untyped) =
lastGreeting = text & " " & who
actions
echo lastGreeting
greet lastGreeting:
echo "Example 1"
greet(lastGreeting, "Hi"):
echo "Example 2"
greet(lastGreeting, "Salute", "Fred"):
echo "Example 3"
greet(lastGreeting, who = "Tom"):
echo "Example 4"
echo "\nLastGreeting: ", lastGreeting
Run
does generate the same type of compile errors:

Defaulting for the previous template parameters doesn't happen!!
**If so, how can I achieve the desired effect of template parameter defaulting
in such a case?**
( _or is this a sad case of you can 't get there from here_ :-( )
