Naming parameters in script

Avisynth accepts in script calling functions with named parameters also without naming them as long as they are in correct order. This however creates problem when arrays are used. Incidentally arrays can not be named. In the following: functionname(width = 720, height = 480, x= 90, y = 100) can also be called as functionname(720,480,90,100) if the order of parameter named correspond to that actually used in the function code. incase of "fname", "ci*[width]i[height]i[x]i[y]i) if script call is fname(1,2,3,4,720,480,x=90,y=100) it is not clear whether 720 and 480 are taken in to i+ array or assigned to width and height as was intended. This scheme is error prone. I suggest that in 2.6 it may be made compulsory to make the names of named arguments be given in script. Should it not be possible to name even array parameters such as [table]i+ ? Vapoursynth does that and appears to be good.

in the instance the parameter list is c.*[ll]b[ss]s[ii]i all parameters can be read as part of the .* Possibly if the param list is c.*bsi one can get correctly. In such cases if the parameters are named for convenience, the plugin writer checking for Defined() and ensuring it is, may be way out.

There is some advantage to putting array of type early in list of args, and forcing user to use the 'optional' argument name (for args following array, name no longer optional), it allows you to extend number of function arguments without breaking existing scripts.
