Hi,
after having followed SICP, I have been irremediably hooked on
Scheme's let, so I added it to my macros. IIRC, I borrowed this
implementation form SBCL's NAMED-LET (it's so short, it's hard to
tell).
I also heavily use a cataphoric IF, which I will now replace by the
single-binding IF-LET, now that I know it exists.
I thought it would be nice if LET@ was available in Alexandria with
the other binding macros.
Regards,
Pierre
