Re: Observations from a C++/Python developer that never used Perl5

The pair constructor seems to be in a different category than the other quoting operators since the expression that it quotes must look like an identifier: https://github.com/rakudo/rakudo/blob/nom/src/Perl6/Grammar.nqp#L1776 token fatarrow {

Re: Observations from a C++/Python developer that never used Perl5

You cannot currently define your own quote-like operators. That will come with true macros (though you could certainly do it via a slang... everything is possible with a slang). But they are operators. Not only are they operators, but they nest other operators. vis: say "These are my args:

Re: Observations from a C++/Python developer that never used Perl5

Quotes are almost a circumfix operator, but they act a bit more like a macro by controlling the parsing of the contents. But you can do some weird things like define your own quote-likes. perl6 -e ' sub circumfix:<>($v) { "{$v}" } ; say B"foo"B ' # output: foo or more verbosely perl6 -e ' sub

Wait, quotes *are an operator* ? If so how would I define them? If the operator returns string, what is the type of its argument? If so that's even stranger -- most languages they're a hard coded bit of syntax -- the closest thing I can think of is in C++11 you can add your own string literal

Re: Observations from a C++/Python developer that never used Perl5

Hi Joseph Welcome, and I hope you'll stick around. Now, I haven't had the time to dig into Perl 6 myself, only to poke at it from time to time. But, while waiting for people who know something to respond, I'll ask you to be a little concise in certain areas. * I can find no concise
