They're all returning the final value, so that is consistent:
>> g: repeat x {eh?} [? x x]
X is a char of value: #"e"
X is a char of value: #"h"
X is a char of value: #"?"
== #"?"
>> g
== #"?"
And loop done the same way:
>> i: 1
== 1
>> t: loop 6[? i i: i + 1]
I is an integer of value: 1
I is an integer of value: 2
I is an integer of value: 3
I is an integer of value: 4
I is an integer of value: 5
I is an integer of value: 6
== 7
>> t
== 7
Here's how to do that Repeat line if it's to hold the string:
>> g: repeat x {eh?} [? x append {} x]
X is a char of value: #"e"
X is a char of value: #"h"
X is a char of value: #"?"
== "eh?"
>> g
== "eh?"
And the reason for the error - the block is
never evaluated, so nothing can be returned.
>> repeat x 0 [] ;Look: nothing shown in the console
>> t: ;So it is equivalent to this line
