Re^5: Unicode infinity

[bliako]

In entirely friendly attitude: I can't stand gnu error messages containing unicode for ellipses and quotes. It's really a pollution. So, In general I am against polluting the language with non-ascii symbols. And my language's alphabet is entirely non-ascii. Let python be the winner in this battle. I think you opened a can of worms :) next will be <= and >= and what about thumbs-up for if(👍 $x){}. And gotos will become again popular just for the sake of goto 😭 Anyway, I should have said that earlier.

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'    
Unrecognized character \x{221a}

nice! Now on to this ❸.❶❹

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

Nope, don't need spaces between symbols and identifiers.

For example,

1 + length
- inf
! f()
g( $z )

can be written as

1 +length
-inf
!f()
g( $z)

etc

But, I like this can of worms :-)

Don't forget ≠ ! I already added them to Language::FormulaEngine and rather enjoy them in the webapp I built with that.
