In Crystal we chose the following: you can have two consecutive string 
literals but only if they are separated by a `\` at the end of the line.

So this is a syntax error:

foo("bar" "baz")

But this is ok:

foo("bar" \
     "baz")

Likewise, this is an error:

["foo", "bar" "baz", "qux"] # most probably we forgot to add a comma

But this is ok:

["foo", "bar" \
  "baz", "qux"]

This way you avoid silly typing mistakes while at the same time you 
allow splitting a string across several lines without having to 
concatenate them at runtime.
