Personally, I like to use this syntax for simple variable
substitution:
PS> $s = "string"
PS> "${s}test"
stringtest
Note the use of curly braces to delimit the variable name. However,
this doesn't work for grabbing an object's property:
PS> "${s.length}test"
test
Doh.
So in this case, I use a new evaluation context like so:
PS> "$($s.length)test"
6test
They're ordinary brackets this time, not the curly ones.
Hope this helps,
