& { # purpose is to reformat scriptblocks # scriptblocks are a common element in many PowerShell structures # and can also be used standalone # to improve readability, this unit identifies the opening and # closing braces and makes sure these braces exist on individual lines # separated from other content (to improve brace alignment) # if a scriptblock is a "one-liner" (start and end brace exist on same line), # then no optimization is done because one-liner are often desired. # the unit also determines whether or not the scriptblock is a parameter # argument.
