Could someone please explain me how to deal with cases where the application of `addargs` creates a function with zero arguments?
Consider for example
```
CFunction f,g,h;
S x,y;

@EDWhyte There is an important piece that the original sympy_tree.py in sdopt-tearing does but solvable.py doesn't: In sympy_tree.py all the possible safe eliminations are stored in a dictionary (unfo…

bc.. sympycore now has a working implementation of how to work with unapplied
functions easily. There are related bugs in sympy now, for example:
In [1]: a = Symbol("exp")

The following definite integral gives the wrong results in both SymPy and SymPy Gamma:
`integrate (x**9-x**2.5556-(x/(x-3.6**70)), (x,1,2))`
The correct answer is about 99.27 ([WolframAlpha](htt…

As discussed in various other contexts before, Devito currently enforces an index addressing scheme based on absolute value with respect to the allocated data of a `Function`. Such a (for lack of a be…
