Re: unrecognized syntax: type[args]

[Damien Mattei <damien.mattei@gmail.com>]

i understand that in kawa there is an immediate evaluation of $bracket-apply$
but here i'm using $bracket-apply$ as a procedure (was a macro in the
past) that will be evaluated later at a point container-eval and
expr-eval are known.

And container-eval and expr-eval are not type in my code but variable
that could be vector,string,hash-table,arrays.... all that could be
indexing by one or more indexes.... [ ] as operator....
