String interpolation

[Behrang Saeedzadeh]

That is concatenation, not interpolation. FYI:
http://en.wikipedia.org/wiki/String_interpolation

And it might be a matter of preference but IMO string interpolation is
more readable than concatenation.

Plus, "Hello #{p.name}" in Java translates to:

"Hello "+p.getName()

Furthermore, for the sake of clarity and readability most people will
write it like:

"Hello " + p.getName() (i.e. with blank spaces around +) which is more verbose.
