Suggestion re the manual

[Rob T]

WRT "exists" being difficult to discover, it's important to keep 
in mind that D is a generic programming language. The "exists" 
concept won't necessarily apply to files, which make prefixing 
much more desirable than embedding the "file" name directly into 
the function (or template) name.

As an example outside from programming, consider how domain names 
are organised,

toplevel = dlang.org
sub-level = forum.dlang.org

We could create a brand new domain, forumdlang.org but that's not 
a great idea do to. Same idea as with exists.

The basic issue is that not much has progressed with programming 
languages over the last century (yes I'm joking) we still use 
text editors to program with (IDE's are noth more than glorified 
text editors), and a side effect of that is searching on text 
strings is kinda silly if you know what I mean.

Really the best way to view a programming language is as if it 
were a strand of DNA, it's something to manipulate, but it has to 
be done carefully otherwise you end up with a lot of warts. We 
need much better tools, one day we may have them, but I'll 
probably in the grave before that ever happens.
