square root question

[ToddAndMargo via perl6-users]

Hi All,

Am I pushing it with the unicodes here?

say sqrt(2)
1.4142135623730951

say 2.sqrt
1.4142135623730951

say ½*2.sqrt
0.7071067811865476


say 2.√
===SORRY!=== Error while compiling:
Malformed postfix call
------> say 2.⏏√

say √2
===SORRY!===
Argument to "say" seems to be malformed
------> say⏏ √2
Bogus postfix
------> say ⏏√2
    expecting any of:
        infix
        infix stopper
        postfix
        statement end
        statement modifier
        statement modifier loop


Many thanks,
-T
