Can you define constants for these numbers like 1, 2, 4, etc?

[Yang, 2015/11/02 20:51:08]

Isnt the point of macros.py to contain those constants that are otherwise
hidden? See those date macros below. I dont think adding another level of
indirection is going to make this more readable. The macro names are descriptive
enough.

+macro REGEXP_IGNORE_CASE(regexp) = (regexp[regExpFlagsSymbol] & 2);
+macro REGEXP_MULTILINE(regexp) = (regexp[regExpFlagsSymbol] & 4);
+macro REGEXP_STICKY(regexp) = (regexp[regExpFlagsSymbol] & 8);

 # We can't put macros in macros so we use constants here.
