Powershell pitfalls

Question

What Powershell pitfalls you have fall into? :-)

Mine are:

# -----------------------------------
function foo()
{
    @(\"text\")
}

# Expected 1, a         


        

Answer 1

Another one:

$x = 2
$y = 3
$a,$b = $x,$y*5 

because of operators precedence there is not 25 in $b; the command is the same as ($x,$y)*5 the correct version is

$a,$b = $x,($y*5)
