int( my_array ) === 4 // <translate><!--T:409--> Same as length</translate>

float( my_array ) === 4.0 // <translate><!--T:410--> Counts the elements</translate>

string(my_array) == "5\n6\n7\n10\n" //<translate><!--T:17--> Note: the last linebreak could be removed in the future</translate>

'5\n6' in my_array == true //<translate><!--T:18--> Note: this is due to how arrays are casted to string, i.e. by imploding them with linebreaks</translate>

1 in my_array == true //<translate><!--T:19--> Note: this happens because 'in' casts arguments to strings, so the 1 is caught in '10' and returns true.</translate>

my_array[] := 57 // <translate><!--T:411--> This appends an element at the end of the array</translate>

my_array[2] := 42 // <translate><!--T:412--> And this is for changing an element in the array</translate>
