I use something in between the two. When a property is fetched, expand
any ${} or %ENVVARS% before returning the value.

This is more flexible than 1, as you can refer to properties before
they've been defined:

product.home = ${common.home}\product
common.home = c:\foo\bar

> 2. Values which are fully dynamic

Is that really a common requirement? Every time I need inline value
expansion it's usually to do with file system paths, and they're usually
values that will never change once the software's been installed, let
alone dynamically at runtime.
