see vector-accessor from (sph vector) instead and create records like #(symbol:type-name value ...).

access vector elements with field names.

this library is supposed to be simpler in definition and usage than previously existing record libraries (rnrs, srfi) and

more powerful by being based on vectors (records) and hashtables (layouts) and their less restricted interoperability.

any vector can be accessed as a record and records can be accessed as vectors.

if type information is desired then for example a symbol type name can be used as the first element of the vector.

vector records have the typical literal vector representation for read/write.

usage:

(define-record my-record a b c)

(define-record my-other-record (a accessor-name setter-name) b (c my-other-c))

(define x (record my-record 1 2))

(my-record-a x) -> 1

(my-record-c x) -> #f

(my-record-c-set! x 3)

syntax

  record-update-b :: record-layout a field-names ...

    create a new vector with field name and value taken from given identifier and variable value.

    example: (record-update layout instance name name-2)

    same as (record-update layout instance (q name) name (q name-2) name ...)
