a. splitting.cr
b. utf8.cr: The cat character 猫 has unicode codepoint 29483 and takes 3 bytes: 231, 140, and 171.
c. object_id.cr: Strings with the same value have the same object_id for performance. That id, of course, could differ from the value given here.
Integers have no object_id because they are created on the stack.
string_symbol.cr: They are not the same.
destructuring.cr
a. union_types.cr
b. hashes.cr
c. compile_runtime.cr
a. var1.cr: The value of var1 is 2; same output for a while instead of if.
b. if_elsif_else.cr: The output is 9 and has one digit.
c. exception_union.cr: The compile-time type of a is (Int32 | Nil); Nil is the type it had when an exception occurred. Use as to ease the compiler.
