The is really operator is only for types:

/value/ is really [ nothing | a boolean | an integer | a real | a string
| a binary string | an array ]

and as of LC8dp7 it is not working to well:
"0" is a string -> true
0 is a string -> true
0 is an integer -> false
0. is a string -> true
0. is a real -> false
"0." is a string -> true

The proposed "is exactly" syntax is comparing two variables (or values)
for equivalence by type and contents.

Whoever came up with the "is exactly" syntax should submit it as an
enhancement to http://quality.runrev.com/
It would be a great addition to the language.
