Shouldn't this be the right idiom to initialize a vector (container) with literals:

use My_Vectors;
V : My_Vectors.Vector := Element1 & Element2 & Element3;

Looks nice, but does not compile (with GNAT), because the compiler cannot make a decision on which "&" function to use where. Is there a way to give precedence to one of the "&" functions? Or some other nice solution? Thanks.

/*
My current solution is to rename one of the functions:

use My_Vectors;

function "+" (L : My_Vectors.Vector; R : My_Element_Type)
   renames My_Vectors."&";

V : My_Vectors.Vector := Element1 & Element2 + Element3;

Not elegant at all.
