# Simple aliases to `New-Object System.Windows.Controls.Widget`, which
# ease parameter definition + method invocation using a hashtable arg:
#
#    $w_btn = W Button @{Content="Text"; Border="2"; add_Click=$cb}
#    $w_grd = W Grid @{Add=$w1, $w2, $w3}
#
# Or augment existing form objects:
#
#    W $w_btn @{Background="Black"; Foreground="White"}
#
# Perhaps even nesting if you can stand the parentheses/curly braces:
#
#    $form = W Window @{Width=800; Height=600; Add=@(
#        (W StackPanel @{Orientation="Vertical"; Add=@(
#            (W Label @{Content="title"; Foreground="Blue"}),
#            (W Button @{Content="Click me"; Background="Red"})
#        )})
#    )}
#
# The `W` shortcut is for WPF, whereas `WF` summons WinForms widgets.
# While `WD` is an alias to System.Windows.Document.xyz elements.
