C++ books do take about it -- just check out the good ones.  This very
problem, if you check out writings from Bjarne or me (see, e.g.,
our proposal for "generalized initializer list" for discussions), is a
problem inherited from the C syntax which permits redundant
parenthesis in declarations, exacerbed by the functional notation.
Check out details from D&E.

this is somehow hard to diagnose, but I guess one could engineer the
front-end to remember redundant parens, but it would be rather low
priority for me.
