I'm working with arrays of arrays of strings, result and ys. I want to
append/prepend a one-element array of strings, [y], to ys. Neither compiles.

string y = "a";
string [][] ys = [];
string [][] result = [];
result = ys ~ [y];
result = [y] ~ ys;

test.d(30): Error: incompatible types for ((ys) ~ ([y])):
'invariant(char)[][][]
' and 'invariant(char)[][1u]'
test.d(31): Error: incompatible types for (([y]) ~ (ys)):
'invariant(char)[][1u]
' and 'invariant(char)[][][]'
test.d(31): Error: cannot implicitly convert expression ([y] ~ ys) of type
invar
iant(char)[][] to invariant(char)[][][]
