Would the approach I suggested for the Python bindings, i.e you would build a
list of options with the current syntax of the utilities from the Perl key-
value list sound reasonable ?
For example, let's say the user calls gdal.Translate("format" => "GTiff",
"src_win" => [100,400,50,50] ) (this is probably not valid Perl syntax, but
hope you got it !), and you would call GDALTranslateOptionsNew(list) where you
would build list = { "-format", "GTiff", "-src_win", "100", "400", "50", "50",
NULL }
