 Nimrod allows user-definable operators.
 Binary operators have 10 different levels of precedence. 
-All binary operators are left-associative, except binary operators starting
-with (or only consisting of) ``^``.

+Relevant character
+------------------
+
+An operator symbol's *relevant character* is its first
+character unless the first character is ``\`` and its length is greater than 1
+then it is the second character.
+
+This rule allows to escape operator symbols with ``\`` and keeps the operator's
+precedence and associativity; this is useful for meta programming.

+Associativity

+relevant char is ``^``.
+
+Precedence
+----------
 
 For operators that are not keywords the precedence is determined by the
 following rules: 
 
-An operator symbol's *relevant character* is its first
-character unless the first character is ``\`` and its length is greater than 1
-then it is the second character.
-
 If the operator ends with ``=`` and its relevant character is none of 
 ``<``, ``>``, ``!``, ``=``, ``~``, ``?``, it is an *assignment operator* which
-has the lowest precedence.
+has the lowest precedence.
+
+If the operator's relevant character is ``@`` it is a `sigil-like`:idx: 
+operator which binds stronger than a ``primarySuffix``: ``@x.abc`` is parsed
+as ``(@x).abc`` whereas ``$x.abc`` is parsed as ``$(x.abc)``.
+
 
 Otherwise precedence is determined by the relevant character.
