Right hand side vs. Left hand side

What : Different sides to an operator e.g. == 
 Why : Proper treatment of the sides of an operator e.g. == results in much functionality

 .left and .right 
 In Free Form Programming Language (ff) the dot operator, namely the dot on your keyboard, allows for accessing parts of an expression! 
 For a given equation e.g. eq, in the ff program below, the lhs or x^2-1+y can be accessed by the expression eq.left and a/b+c by the expression eq.right. 
 eq = (x^2-1+y == a/b+c);

lhs = eq.left;

show lhs;

rhs = eq.right;

show rhs;

save as sides;
 
 Output 
 
 .box {
 width: 200px;
 height: 70px;
 background-color: hsla(89, 43%, 51%, 0.3);
 border: 2px dotted orange;
 padding: 10px;
 margin: 10px;
 }
 
 
 "lhs" → -1 + x^2 + y 
 
"rhs" → a/b + c
 
 
 The programmer is not required to use a symbol e.g. eq for this . access, as long as using the ( ) operator the results would be the same: 
 tmp = (x^2-1+y == a/b+c).left;

show tmp;

save as lhsrhs;
 
 Output 
 
 .box2 {
 width: 200px;
 height: 50px;
 background-color: hsla(89, 43%, 51%, 0.3);
 border: 2px dotted orange;
 padding: 10px;
 margin: 10px;
 }
 
 
 "tmp" → -1 + x^2 + y 
 
 
 ⊕ 
 In Free Form Programming Language (ff), the Symbol ⊕ is one of several unassigned operators. 
 
 As you can see the . operator works perfectly even if the operator in use is not defined! This is a core language aspect of ff that allows undefined variables as well as undefined functions and undefined operators alike. 
 
 eq = (x^2-1+y) ⊕ (a/b+c);

lhs = eq.left;

show lhs;

rhs = eq.right;

show rhs;

save as sides;
 
 Output 
 
 .box {
 width: 200px;
 height: 90px;
 background-color: hsla(89, 43%, 51%, 0.3);
 border: 2px dotted orange;
 padding: 10px;
 margin: 10px;
 }
 
 
 "lhs" → -1 + x^2 + y 
 
"rhs" → a/b + c
 
 
 Try different operators. 
 eq = (x^2-1+y) <= (a/b+c);

lhs = eq.left;

show lhs;

rhs = eq.right;

show rhs;

save as sides;
 
 Output 
 
 .box {
 width: 200px;
 height: 70px;
 background-color: hsla(89, 43%, 51%, 0.3);
 border: 2px dotted orange;
 padding: 10px;
 margin: 10px;
 }
 
 
 "lhs" → -1 + x^2 + y 
 
"rhs" → a/b + c
