myarray has length = 0 so myarray[0] is out of bounds
"~=" will append to a dinamic array

so it's very simple:
myarray ~= "abc...";

char [] [] thanksgiving;

thanksgiving ~= "turkey";
thanksgiving ~= "tort";
thanksgiving ~= "footbal";

However ive been playing with it , and Im not sure how to delete the 2nd
element, and have the array resize so that length is 2 and it contains
"turkey" and "football"

delete thanksgiving[1];
thanksgiving[1] = null;
thanksgiving.length = 2;

not working

you can assign them manually of course, im missing something ?

Don't do:
thanksgiving[1..thanksgiving.length-1] = thanksgiving[2..thanksgiving.length];
thanksgiving.length = thanksgiving.length-1;

The compiler will accept that (and actualy runs fine on some DMD versions)
but the manual says it illegal.
inserting with the same slicing technic will not run as expected.

you must cycle through the array to shift the elements.
do the same thing to insert.

but, of course, arrays aren't suppose to be used when you need to
delete and inserting elements frequently. I guess that's why
Walter doesn't want to implement the "smart" overlap slicing.

I think delete only works for associative arrays, not regular ones. So 
what you're really doing is deleting the string object itself, not the 
array slot.

So I guess you're stuck with manually moving the elements down.

[ This is another example why delete shouldn't be used to delete slots 
in associative arrays. It just soooo inconsistent and confusing. We need 
a different operator/method for deleting array slots!]
