with expressions, doesn't work with variadics, introduces template

does that work?
string escapeD(string a){
import std.array:replace;
return `r"`~a.replace(`"`,`" "\"" r"`)~`"`;
}

Thanks! your solution is more robust (minus some caveats i mentioned) and
also trivially extends to variadics.

Is there a way to do the following lazily:
writelnIfNotEmpty(T)(T a){
auto b=text(a);
if(b.length)
writeln(b);
}
ie, without using std.conv.text (which needlessly computes an intermediate
string, which could be quite large) or launching a separate process ?
writelnIfNotEmpty(""); //doesn't pri

Thanks, but I don't see how that
Currently (on OSX) I can runtime load a D dll from a C program, but not
from a D program, which seems silly.
Is it possible to runtime load a D shared library as a standalone (ie
without sharing GC, runtime or any other data), treating it as if we were
loading from a C program (making no attempt a

is there a function to get the inverse of escapeShellCommand?
ie:
assert(escapeShellCommandInverse(` foo 'hello world' `)==[`foo`, `hello
world`]);
Is there a function to do this?
If not and I/someone writes it, is there interest to add it to std.datetime?
Duration t = ...;
t.to!string => 5 secs, 889 ms, and 811 μs
t.round.to!string=> 5 secs
t=...;
t.to!string => 889 ms, and 811 μs
t.round.to!string=> 889 secs
Use case: shorter logs

is there anything more efficient than this?
auto byKeyValue(T)(T a)if(isAssociativeArray!T){
return a.byKey.map!(b=>tuple(b, a[b]));

how to iterate over an AA by key-value pair (tuple)?
use case:
avoid interrupting UFCS chains, eg:
foo.generate_aa.byKeyValue.filter!(a=>a[0].isLower).map!(a=>a[1]) ...
of course I could roll my own function but I was wondering if there's
already a way.
I reported this here some time ago:
http://d.puremagic.com/issues/show_bug.cgi?id=11501 (dup of
http://d.puremagic.com/issues/show_bug.cgi?id=8298)
and there's a pull request ready, not sure why it isn't being merged
