Regarding your immediate need for a growable vector type, Guile implements VLists <https://www.gnu.org/software/guile/manual/html_node/VLists.html>, which can take the place of standard lists, but also offer constant- time index referencing like vectors. VLists are functional data structures and are thus immutable, but this is natural for idiomatic Scheme code. >i want to use GOOPS but i do not understand how the superclass could be >accessed,used, instanciate... >for example in the doc there is: >(define-class <my-complex> (<number>) r i #:name "Complex") > >seems <number> superclass is of no use > >for my growable vector i would like to use array as superclass? >but perhaps should it be just a slot as array are a subset of growable >array ,so a subclass > >anyway if i write something ike that: >(define-class <gvector> (<array>) ..... >how can i use the <array> object? > >i think perhaps i should not define a superclass or <object> as super >class.... >any advice welcome... > >Damien -- Atom
