Re: can a method name contain a funny character?

Thanks for the in-depth analysis. My misunderstanding was about what an identifier considers a number; I have no well-thought-out ideas on the subject of what an identifier ought to be. Having the docs mention that "number" means only characters with a Unicode Property GeneralCategory of Nd might

Re: can a method name contain a funny character?

To be clear, I expect that "number" in "followed by zero or more word characters (alphabetic, underscore or number)" means "if Unicode thinks it's numeric, you can use it in an identifier after the first character." I don't expect that every numeric codepoint in Unicode must evaluate to number in

Re: can a method name contain a funny character?

If we don't want to get the "line noise" libel all over again, there are some features of the language that should probably go unmentioned for a while. The ability to use non-ASCII characters in names may be perfectly justifiable. When the cognoscenti have produced enough decent code showing how

@Parrot Raiser and @Luca. I will make sure to add Texan alternatives in case other people need to take over. I use triangle symbols to make internal symmetries in the code visible, and I have no problem pronouning or typing them. The code is substantially more readable with them. The same is

Re: can a method name contain a funny character?

Mathematical symbols might be a legitimate case, since they are generally pronounceable. Otherwise, special characters cause problems both in entry from the keyboard and thinking about the code. (What does it sound like if you describe it to yourself? foo.heart?) On 4/12/16, Luca Ferrari

Why? Perhaps you are confusing taste and good sense. The heart is just an example. My intention is for a mathematical symbol and a mathematical meaning. I see nothing wrong with that. Parrot Raiser schreef op 2016-04-12 01:06: I hope I never run across code written by someone who thinks this

Re: can a method name contain a funny character?

Thanks Larry for the answer and the great language. It is quite ok for me to start alphabetically. I use the funny char to indicate a particular aspect shared by a bunch of subs operators and methods. So I tried: method term: { "Mel G.".say } However, that gives me: Bogus postfix

Re: can a method name contain a funny character?

You have to write it like this: class Foo { method ::('❤') { "mem heart".say } } my Foo $foo .= new; $foo.'❤'(); Other than that, only names beginning alphabetically are allowed. You could work around this on the caller end with a postfix:<❤>, but that would be an

can a method name contain a funny character?

Hi perl6 fans, I can use funny characters in operators or in sub names (using term:<...>). However, when I try the same thing with an operator as in: class Foo { method term:<❤> { "mem heart".say } } my Foo $foo .= new; $foo.❤; I get: Malformed postfix call That is unexpected for me,
