Hiya Carl:
Might be good to check all type predicates for R3. Myself I've made use of
only
a few of the datatypes - but with REBOL3 coming along would be a good
time to review them. Know that all tests are correct would "harden" rebol.
BTW: I noticed something interesting:
>> source email?
email?: native ["Returns TRUE for email values." value [any-type!] 43]
Us "old hands" know that 'native means that this function is coded in C
and compiled into the binary _But_ what does the number 43 mean?
again email?: native ["Returns TRUE for email values." value [any-type!] 43]
