$bracket-apply$ of SRFI 105 not implemented

[damien-mattei]

hello, i can not use $bracket-apply$ and find no occurence of it in the repository.I suppose it is not implemented. In theory it should be as curly infix is included in neotreic expression incuded in sweet expressions. Bienvenue dans DrRacket, version 7.7 [3m]. Langage: sweet-exp racket, avec débogage; limite mémoire : 128 MB.

    (define T (make-vector 5))
    '{T[3] <- 7}
    '(<- (T 3) 7)

{T[3] <- 7}
. set!: not an identifier in: (T 3)

normally this should expand like:

'{T[3] <- 7}
'(<- ($bracket-apply$ T 3) 7)

{T[3] <- 7}
7

{T[3]}
7

i suppose sweet exp transforming T[3] in T(3) and is ignoring the $bracket-apply$
