Assuming a string
A = 'abc';
How to repeat it for several times, say 3 times, with a delimiter ',', so that to obtain:
'abc, abc, abc'
Is there a neat solution to do so?

Ran in:
A = 'abc';
B = join(repmat({A},1,3),', ');
B = B{1}
B = 'abc, abc, abc'
C = join(repmat(string(A),1,3),', ') % string output!
C = "abc, abc, abc"
D = sprintf('%1$s, %1$s, %1$s',A)
D = 'abc, abc, abc'
