TCO to the max!
...
Close #446 .
Currently tested by disassembling and tracing various recursive jq
programs by hand under valgrind. An improved test framework that
can test for errors and specific bytecode patterns is in
development.

Add ?, .[]?, and .. operators
...
Make XPath-like `//a/b` recursive structure traversal easier in jq,
which then becomes:
..|.a?.b?
The `?` operator suppresses errors about . not being an array or object.
The `..` operator is equivalent to calling the new `recurse_down`
built-in, which in turn is equivalent to
recurse(.[]?)
Note that `..a` is not supported; neither is `...a`. That could be add
added, but it doesn't seem worth the trouble of saving the need to type
a '|'.

Refactor assignment.
...
New version is much more elegant and probably slower. Uses
library functions implemented in jq rather than dedicated opcodes.

Refactor function argument passing into what it always should have been.
...
Most visible change is that error messages when a function is called
with the wrong number of arguments are much better.

Extend {foo} syntax to allow {"foo"} as well.
...
Useful when "foo" contains unusual characters. Should help with
the issues #7 , #38 , #40 , #42 .

A string interpolation syntax that I don't hate. Also tests.

You can interpolate values into strings using \(this syntax), e.g.
"best \("str" + "ing") ever"
