Substitution Construction Conclusion Typing equations What we would like to type 1 symbol a; 2 symbol w; 3 symbol t; 4 symbol phi; 5 6 formula f = a ∗ sin(w ∗ t + phi ); 7 8 double y = f(a = 5.0, w = 2 from the syntax 1 symbol a; 2 symbol w; 3 symbol t; 4 symbol phi; The idea a, ω, t, ϕ should all have a unique type The problem How to produce a different type everytime a new symbol is created? The as default template parameter 1 template 2 struct symbol {}; The result 1 symbol x; 2 symbol y; 3 4 std :: cout << std :: is_same_v << std :: endl;

backslashed LaTeX symbol name followed by tab. For example, the variable name δ can be entered by typing \delta-tab, or even α̂⁽²⁾ by \alpha-tab-\hat- tab-\^(2)-tab. (If you find a symbol somewhere, e.g code, that you don't know how to type, the REPL help will tell you: just type ? and then paste the symbol.) Julia will even let you shadow existing exported constants and functions with local ones (although operator_precedence(:+=), Base.operator_precedence(:(=)) # (Note the necessary parens on `:(=)`) �→ (0, 1, 1) A symbol representing the operator associativity can also be found by calling the built-in function Base.
