Idiom #153 Concatenate string with integer

Create the string t as the concatenation of the string s and the integer i.

import std.conv : to;
string t = s ~ to!string(i);

The "cat operator" is built in the language. The conversion of the integer is a library routine.
import std.format : format;
string t = "%s%d".format(s, i);

using the format function
t = '{}{}'.format(s, i)
t = '%s%s' % (s, i)
t = s + str(i)
t = f"{s}{i}"

The f in front of the string makes it a Literal String, in which you can put expressions inside brackets
t : String := s & Integer'Image (i);
