Re^6: Unicode infinity

I think you opened a can of worms :) next will be <= and >= and what about thumbs-up for if(👍 $x){}.

If you can do this:

perl -Mutf8 -wle 'use constant π=>3.141;use overload "sqrt"=>\&sr;sub sr{sqrt shift}print sr π'
1.77228665852903

This seems reasonable:

perl -Mutf8 -wle 'use constant π=>3.141;use overload "sqrt"=>\&√;sub √{sqrt shift}print √π'

√π looks cool but I know perl needs space √ π or parens √(π).	[reply]

Nope, don't need spaces between symbols and identifiers. For example, `1 + length - inf ! f() g( $z )` [download] can be written as `1 +length -inf !f() g( $z)` [download] etc	[reply] [d/l] [select]
