in thread Order of evaluation/interpolation of references

Admittedly I'm pretty far off topic from the thread, but I prefer:

print "Take ", 1 + 4, "\n";

and like this even more:

printf "Take %i\n", 1 + 4;

But the prospect of a cleaner syntax to interpolate more... stuff than we currently can is interesting.

    That doesn't solve the problem though:
    sub X { state $x; $x = shift; \$x; } print ${X(1)}, " ", ${X(2)}, "\n"; print ${X(1)}, " "; print ${X(2)}, "\n"; printf "%d %d\n", ${X(1)}, ${X(2)}; printf "%d ", ${X(1)}; printf "%d\n", ${X(2)}; __END__ 2 2 1 2 2 2 1 2

    The curse of the trivial example. Would you agree that first is a lot easier on the eyes than the latter two?:

    print "And the set contains [ { sort @a } ]\n";; And the set contains [ brown dog fox jumps lazy over quick the the ] printf "And the set contains [ %s ]\n", join ' ', sort @a;; And the set contains [ brown dog fox jumps lazy over quick the the ] print "And the set contains [ ", join( ' ', sort @a ), " ]\n";; And the set contains [ brown dog fox jumps lazy over quick the the ]

    Even with the complication of the p5 syntax, it's still nicer to my eyes:

    print "And the set contains [ @{[ sort @a ]} ]\n";; And the set contains [ brown dog fox jumps lazy over quick the the ]

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

    The start of some sanity?
