That just shows how versatile lisp is, you are not bound to just one.
Seriously though, any language with macros gives you this feature/plague, even elixir. You just have to show restraint.

@OvermindDL1 You could define a Sigil for something like that. This has the advantage that you don’t need to use "" around whatever you pass in.
I took the idea of creating a Symbolic Math library that used Elixir’s AST and started tinkering a little. The result is symmath.
It is still far from finished, and probably contains some bugs (I haven’t gotten around to writing tests yet, as the library is still in full flux), but it really is a lot of fun to work on.
Some code examples:
iex> import Symmath
iex> f = expr(1+1)
Symmath.expr(1+1)
iex> simplify(f)
Symmath.expr(2)
iex> g = expr pow(2*x-3, 3*pi)
Symmath.expr(pow(2 * x - 3, 3 * pi))
iex> g |> deriv
Symmath.expr(pow(2 * (3 * pi) - 3, 3 * pi) * (0 * pi + 3 * 1))
iex> g |> deriv |> simplify
Symmath.expr(3 * pow(6 * pi - 3, 3 * pi))
Both the simplification and the derivation can still be improved (Things involving multiple applications of the chain rule will go in an infinite loop right now, for instance). Also, there isn’t support for trigonometric functions or logarithms yet.
Still, the basic idea is there, so I’m interested about what you think

I’m implementing Rex a tiny concatenative language on top of Elixir syntax, currently it’s only an experiment on just taking an Elixir quoted expression, transforming it into a post-fix ast (what I call a Rex AST). So basically if you have some elixir like 1 + 2 it gets into rex ast: 1 2 +, then this rex ast is basically transformed into a list of functions each taking a stack, so, for example the 2 function returns something like [2 | stack] and + operates on the two top level values on the stack. Currently rex is just a toy will see how it goes, and of course being on top of Elixir syntax has some particularities, be sure tu check the README if you get interested. 
Cheers.
