instead of one. Obviously, it works, but it's not as clean or elegant.
So use an enum and string mixins:
import std.stdio;
enum bar = q{
writeln( "The bar has opened." );
scope( exit ) {
writeln( "The bar has closed." );
}
};
void main( ) {
writeln( "Entering..." );
mixin( bar );
writeln( "Exiting..." );
}
Output:
Entering...
The bar has opened.
Exiting...
The bar has closed.
