Well, the problematic point are compile-only words:

' if execute 
:1: error: Interpreting a compile-only word
' >>>if<<< execute
Backtrace:
$7F4AD828A598 throw 
$7F4AD828ABE0 execute 
$7F4AD828BA68 name?int 

if 
:2: error: Interpreting a compile-only word
>>>if<<<
Backtrace:
$7F4AD828A598 throw 

Looks similar, but is not the same. ' IF already fails, the EXECUTE part is 
not even reached.  You could interpret that statement of the standard that 
EXECUTE should do the actual action (here: throwing an error), in Gforth, 
it's ' which throws the error.
