Re: Thx, St. Larry, for the Beauty of Sigils

Just to be sure I understand the problem.

because a variable is a bareword you can't just type ?

meth = "name"
obj.meth()
[download]

In JS you could solve this with a bracket syntax to look up an attribute obj[meth]()

Console demo:

> obj = { name : function () {return "called" } }
Object { name: name() }

> meth ="name"
"name"
> obj[meth]()
"called"
[download]

But in python you need a function getattr() ?

Yes, but the bracket subscript trick works for dynamic class names, thus: `globals()["CLASSNAME"]` 🤢 I wrote about this before at http://redd.it/6epqi5#did1j9b and I also have a collection for several programming languages at https://stackoverflow.com/q/26402047. ES6 classes are missing, and `eval('CLASSNAME')` is the answer. tl;dr if the language does not have sigils on identifiers, this topic is a pain in the butt.	[reply] [d/l] [select]

I like sigils, probably also because my first language was BASIC. But I still think they make code more readable, kind of Hungarian Notation Parsing non sigil languages is hard without syntax highlighting. * And isn't readability part of the Zen(terfold) of Python? ;) But some things are unfortunately solved in Perl 5. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice} *) On a side note: I remember having problems with English too, where the same word can sometimes be a verb, adjective and noun, where other languages have grammatical suffices. Headlines in the English newspapers are still a riddle...	[reply]

Here is another story about the Hungarian_Notation: http://www.folklore.org/StoryView.py?project=Macintosh&story=Hungarian.txt. Headlines in the English newspapers are still a riddle...
