This seems to partially reduce Defender falsely identifying this as a threat. Abitrary things seem to matter, like using _div64 instead of 64-bit operations.
The many faces of EForth
EForth is a delightfully minimalist approach to Forth originated by Bill Muench and Dr. C. H. Ting.
In its original form metacompilation is avoided.

EForth Quirks
EForth uses FOR..NEXT in favor of DO..LOOP:
FOR/NEXT.
This construct has the odd property that it iterates one "extra" time for zero.
: FOO 10 FOR R@ . NEXT ; FOO
10 9 8 7 6 5 4 3 2 1 0 ok
To permit a more ordinary loop the AFT word is used in the sequence FOR..AFT..THEN..NEXT.
: FOO 10 FOR ( 1st time only ) AFT R@ . THEN NEXT ; FOO
9 8 7 6 5 4 3 2 1 0 ok
The even more enigmatic FOR..WHILE..NEXT..ELSE..THEN is used in place of DO..LEAVE..LOOP.
It allows a while condition to early out of a counted loop.
