I have done two little benchmarks, using dmd 2.047, compiling just with "dmd test.d":

import std.c.stdio: printf;
void main() {
    printf("%d\n", 10);
}


import std.stdio: writeln;
void main() {
    writeln(10);
}

The program with printf compiles in 0.05 seconds, and the binary is 101_404 bytes, while the program with writeln compiles in about 0.30 seconds and produces a binary of 235_036 bytes, the asm shows tons of templates and functions.
