-Design Notes for a Boolean Type in Gawk
-
-1. A new function  bool(val)  converts val to bool, returning Boolean TRUE
-or FALSE.  This is the generator for boolean values and is enough to have
-instead of predefining new variables TRUE and FALSE.
-
-2. Assigning from a boolean value copies the bool type.
-
-3. Boolean variables have numeric values 1 and 0 respectively, and string
-values "TRUE" and "FALSE".  Thus they differ from other variables where a
-"false" value must be zero and null.
-
-Given:
-
-       true = bool(1)
-       false = bool(0)
-
-this implies all of the following:
-
-       print(true) --> "TRUE"
-       print(false) --> "FALSE"
-       Same for %s in printf
-       Same for bool_var ""
-       printf %d gives 0/1
-
-4. typeof() returns "bool".
-
-5. Numeric operators treat booleans as numbers.  asort() sorts booleans before
-numbers, and false before true.
-
-6. These string function generate a runtime fatal error
-if given an argument / target of boolean type:
-
-       gsub sub
-
-These functions merely treat the value as a string
-but issue a lint warning.
-
-       substr  match   index   gensub
-       length  split   patsplit
-       tolower toupper
-
-7. Updates to API needed for an additional type, and the table
-for requested vs. returns.
-
-8. The following extensions need revising:
-
-       - JSON extension
-       - dump / read array extensions
-       - what else?
