Not in a function, on a function - for example:
>> age: func [][print "I am 22" return 0]
Using just age will evaluate the function:
>> age
I am 22
== 0
Using the get-word :age appears to do nothing, but that's because it
retrieved the function instead of evaluated it:
>> :age
>> probe age
I am 22
0
== 0
>> probe :age
func [][print "I am 22" return 0]
It appears to do nothing different when using word!s as variables for
integers, strings, etc, because in those cases, evaluating it just retrieves
it.
