There are a few neat ways to make it work nicely. One is to access the
value. That is,
v[2,1]=x[]
Another is to assign as a matrix:
v[2:2,1]=x
Automatic conversion between single-value arrays and numbers could be
problematic, if care isn't taken. For example, what happens if v is an
Array of type Any? Does it store the value, or does it store the array
holding the value? Note that it matters when it comes time to modify the
entry.
