Let's say I want to define a mutable string:

char[] a_tmp = "abcd";  // immutable ref
char[] a;
a[] = a_tmp; // mutable copy of immutable data.

OR..?

char[] a = "abc" ~ "d";

Is there a simpler or more direct syntax?

The ".dup" property will duplicate an array:
 char[] a = a_tmp.dup;

try const .... as in
---------------------
import std.c.stdio;

void nctest() {
	char[] a = "abcd";
	char[]b = a;
 	printf( "char[] a = 'acbd'\n" );
 	printf( "char[] b = a;\n=>\n" );
	printf( "a=%.*s\n", a );
 	printf( "b=%.*s\n", b );
 	printf( "b[2]='2'...\n" );
 	b[2] = '2';
	printf( "a=%.*s\n", a );
 	printf( "b=%.*s\n", b );
}
void ctest() {
	const char[] a = "abcd";
	char[]b = a;
 	printf( "const char[] a = 'acbd'\n" );
 	printf( "char[] b = a;\n=>\n" );
 	printf( "b[2]='2'...\n" );
	printf( "a=%.*s\n", a );
 	printf( "b=%.*s\n", b );
 	printf( "b[2]='2'...\n" );
 	b[2] = '2';
	printf( "a=%.*s\n", a );
 	printf( "b=%.*s\n", b );
}

int main( char[][] args ) {
	nctest();
	ctest();
	return 0;
}
------------------------
output (as one would hope is)
char[] a = 'acbd'
char[] b = a;
=>
a=abcd
b=abcd
b[2]='2'...
a=ab2d
b=ab2d
const char[] a = 'acbd'
char[] b = a;
=>
b[2]='2'...
a=abcd
b=abcd
b[2]='2'...
a=abcd
b=ab2d
