Method precedence

Method precedence is controlled by the following two method separators: . and ->.

1 + 25.sqrt      # means: 1 + sqrt(25)
1 + 25->sqrt     # means: sqrt(1 + 25)

The rules are the following:

• . binds the method to the object which precedes the dot

• -> makes everything from its left-side an expression and applies the method on the result

The infix backslash (\) removes any leading or trailing whitespace at that current position and it's useful for expanding method calls on multiple lines:

say "abc".uc      \
         .reverse \
         .chars

is equivalent with:

say "abc".uc.reverse.chars
