Re: syntax? in kawa/scheme

[Damien Mattei <damien.mattei@oca.eu>]

i modify a SRFI 105  curly infix parser to move some function towards 
macro, then to pre-parse the code on the fly at the pre-compil stage of 
the macro,then use the pre-parsed code in the expansion phase. Finally 
the run-time execution of the generated code will be faster as no 
parsing will be done at this run-time phase. (exmple : a mathematic 
formula is known and will not change at run-time ,the infix to prefix 
operator precedence algorithm can be applied before runtime) . Prior i 
parsed s-expr now it will be syntax expression, the logic is the same 
but the code will change, instead of procedure or quoted procedures or 
form it will be syntax objects. For the operator precedence i need to be 
able to compare equality of some operator in a syntaxic form (like #'*, 
#'+ etc...) I admit as there is no native curly-infix srfi 105 in kawa 
it is already done by a parser in command line. (this more easy in Guile 
but very few scheme implement SRFI 105 anyway so i will reuse this code 
in the future)
