Goto start or end of visual selection

[SeSodesa]

I find myself wishing for this feature frequently, so I am creating this discussion. Basically, I often have cursors with visual selections at different columns on multiple lines, and would benefit from being able to collectively jump to the start or end of each selection after surrounding said selections with parentheses. For example, having a comma-separated list, which first gets surrounded with parentheses and then prepended with a function name, to call a function with the comma-separated list as its arguments. In the below example, | is the position of the cursor:

1. a, b,|c # selected (part of) line
2. (a,b,c|) # ms(
3. |(a,b,c) # gvs
4. (a,b,c|) # gve

As in the above example shows, the key combinations could be gvs for goto Visual Start and gve for goto visual end.

You can do "Flip selection cursor and anchor" Alt-; but maybe that's not what you want?

By the sound of it, it might actually suffice. I'll give it a whirl later.
