I see little value in srfi-105.  Who would use it and why?

If you want infix notation with Scheme semantics, you
might find my "KaShell" experiment interesting:
     http://kashell.org/
(KaShell was previously called "q2".)
There are some examples/tests in gnu/q2/testsuite in the source-code.

KaShell has infix operators, with precedence - without reserved operators.
(While not implemented, a 'define-operator' would be conceptually
similar to define-syntax, but with precedence levels.)

On goal of KaShell is to be a nice language for REPL, specifially
like a "rich shell" with typed values.  That is why it avoids
needless parenteses and semi-colon-like delimiters.
Instead, KsShell uses indentation.

Large parts of the syntax I haven't decided on yet.  You can "fall back"
on using Scheme macros:
     let ((x (3 * 4))) (x + 20)
which is equivalent to Scheme:
     (let ((x (* 3 4))) (+ x 20))
but of course that is not very satisfactory.

I haven't worked on KaShell in almost 5 years, but hopefully I'll
get back to it someday.  Until then, maybe someone will be inspired.
