<lloda>how to destructure an alist? match only works with fixed order

<gjanssens>Hi, can anyone point me at a good example of using a function as the #:on-error unwind handler in the call-with-error-handling function ?

<gjanssens>Rather than simply using 'backtrace (still undocumented btw) I'd like to store the backtrace in a global variable to pass back into the C calling code

<gjanssens>I'm having some difficulty figuring out how that is done :(

<gjanssens>Ah found it (soon to appear in gnucash code :)

<ecraven>how complex is the implementation of syntax-parameters?

<ecraven>is this something that is rather easy to add to an implementation?

<civodul>ecraven: in psyntax, syntax parameters look quite easy

<ecraven>civodul: would you happen to know in which source file syntax-parameters are defined?

<civodul>in ice-9/psyntax.scm

<civodul>search for 'syntax-parameterize'

<civodul>the whole file is intimidating but that part less so ;-)

<rekado_>lloda: I’ve been wondering the same. I’d like for a more powerful match (and sxml-match) that doesn’t worry about order.
