The following code compiles fine with the command "dmd test.d"
import std.array, std.algorithm, std.algorithm, std.string;
void main()
{
int[string] s;
auto a = join(map!(a=>format("%s %d", a, s[a]))(s.keys));
}
However, if I try to compile it with "dmd -inline test.d", I get
this error message:
test.d(5): Error: function D main is a nested function and cannot
be accessed from std.array.join!(MapResult!(__lambda2,
string[])).join
The above test was performed with DMD 2.063 on OSX.

Interesting -- I have a similar problem when compiling a program using schwartzSort with the -debug flag:
import std.algorithm, std.range;
void main()
{
size_t[] x = [4, 9, 3, 2, 1, 10, 8, 5, 7, 6];
size_t[] i = iota(x.length).array;
schwartzSort!(a => x[a], "a < b")(i);
}
This compiles fine with dmd -inline but generates a similar error message when dmd -debug is used:
/opt/dmd/include/d2/std/algorithm.d(9117): Error: delegate schwartz.main.__lambda2!ulong.__lambda2 is a nested function and cannot be accessed from schwartz.main.schwartzSort!(__lambda2, "a < b", cast(SwapStrategy)0, ulong[]).__lambda1621!(ulong, ulong).__lambda1621
/opt/dmd/include/d2/std/algorithm.d(9117): Error: delegate schwartz.main.__lambda2!ulong.__lambda2 is a nested function and cannot be accessed from schwartz.main.schwartzSort!(__lambda2, "a < b", cast(SwapStrategy)0, ulong[]).__lambda1621!(ulong, ulong).__lambda1621
