(expression)

["Ruud H.G. van Tol" <rvtol@isolution.nl>]

Just an innocent example:

? my(i=3, n=3); n + (while(i--, n++);n)
  ***   syntax error, unexpected ')', expecting )-> or ',': 
...,n=3);n+(while(i--,n++);n)
*** ^-

? my(i=3, n=3); n + if(1, while(i--, n++);n )
%2 = 8


Would it be useful to allow/support (expression)s like in the first format?
