Counting parameter in a function call

[lisa-asket]

Have found that I can use count-matches to campute tho number of arguments

in a function.



M-x count-matches ,



Now I have to extend this to an elisp function so that I can select the region

of the function, so that it returns me the number in it.

I want to write a function that counts tho number of entries in a function call

after selecting a region.



For instance, the following will count to 6 and the result displayed in the 

modeline.



@myfunc{A, B, C, D, E, F}
