operator <= method
Returns true
if this precedence represents a looser, or equal, binding
than other
; that is, parsing ambiguities will be resolved in favor of
nesting the expression having precedence other
within the expression
having precedence this
, or, if the precedences are equal, parsing
ambiguities will be resolved according to the associativity of the
expression precedence.
Implementation
bool operator <=(Precedence other) => _index <= other._index;
