Wrote some unittests today and thought, this feature is useful when one wants
easy sql statements (in, e.g. unittests).

string typeName="Employee";
int[] ids=executeVector!int("select ID from Objects where type='\{typeName}'");

Meh, I find the placeholders to be much better (safer too):

db.query("select id from objects where type = ?", typeName);

I generally feel the same way about all the interpolated
strings. Plain old format("%s", var); works for me.

I use it too, but found it hard to maintain/check ordering and meaning of
parameters when you edit the query, add or remove parameters.

It's also non-trivial to implement such functionality, since MS (and Oracle,
afaik) require named parameters.

Isn't that a small price to pay to avoid SQL injection attacks?

Best,

Yes.

Ruby has that to:
var = 42
puts "The value of var plus 7 is #{var + 7}"

Actually, that's pretty common in scripting languages. Although, I'd be 
happy at least with a a good string templating lib. Something like:

auto str1 = "The value of $name$ is $val$".render( ["name":"myVar", 
"val":"17"] );

auto str2 = "Alternate delimiters are ::what::".render( ["what":"useful"], 
"::" );

That'd be more general anyway.

std.conv.text can do this job just fine, bar the "uuu not found" bit.
