I agree with Ary that grep hits a lot of false positives and all the
formatting tricks don't work with other people's code, plus I've never liked
IDES. Dscanner's D declaration finder has become indispensable in the short
time I've been using it, to the point where I dread going back to searching
for C declarations and getting stuck with grep again.

the only bad thing i found with this style is that after some time you
really start noticing the absense of whitespace in declaraions, and it
annoys you. so the first thing you want to do with someone's code is to
ADD THAT WHITESPACES! somehow it becomes most frustrating element of

In Ruby I search def some_name and I find it. In Go I can probably
search func some_name. In Rust, fn some_name.
Browsing some C code for Ruby I search with regex with ^some_name

I really don't see how changing the function signature syntax in D would help anything, and it would force all existing code to be changed (be it immediately or just when the compatability flag finally goes anyway). Sometimes, syntax improvements are worth it, but in general, it's just not worth messing with the syntax unless the language is still in flux enough that you don't care at all about breaking existing code.

I'm not familiar enough with the syntax grammar to say for sure whether or not this would make it easier to parse the language. If it does, I wouldn't think it would make it much more simple. One question is how would you declare a function pointer? Current : void function() myfunction; YourIdea: func void function() myfunction; This seems a little odd/redundant. I suppose you could change the syntax to something like this: func void myfunction(); But then you wouldn't be able to know if that was a function pointer or a function declaration. I'll finish by saying that at first glance, I'm not sure if adding this extra keyword will help readability much. I've never really had problems distinguishing between functions and other things. That being said, maybe I've been programming in C-like languages too much so take that with a grain of salt.
