[ok now *really* to gretl-devel] Am 06.03.2012 10:59, schrieb Sven Schreiber: [p.s. to gretl-devel only:] A general syntactic question about those pointer-style arguments: Given that hansl is usually very concise, is it really always necessary to define/initialize the object in a separate line? What I mean is, instead of: <hansl_snippet> matrix argument_to_be eigensym(foo,&argument_to_be) </hansl_snippet> would it be possible to do something like: <hansl_snippet> eigensym(foo,&[matrix myarg]) </hansl_snippet> Note the added '[matrix ...]' -- I am not proposing to use the old syntax and simply create the argument on the fly and guess its type, which would not catch typos for example (if really previously defined objects are meant). This is really just about saving the extra line and hopefully make hansl even more readable. I know tastes will differ here (especially those of the C people...). thanks, sven
