In Perl 5 many people use the syntax to assign the value of a complicated

which is very handy and used many times, I completely agree.
But as you said:
In Perl 6, we have a different syntax for that, by using a pointy block:
if frobnicate(42) -> $x {
say $x
}
which is way more elegant. Should this make it wise to have a compile
time warning for the former then?
Generally, in Perl 5 and Perl 6, when comparing against a constant, you could
consider teaching yourself to always put the constant on the left-hand side:
but that applies only when you compare with a constant. (And to be
honest, sounds like a suggestion from the 80')
