It's interesting that you can use `Function.__new__(cls, integer=True)` for `UndefinedFunction`s like `Function('f', interger=True)` but not for subclassese of `Function`.
Now things like `(2*f.shape[0]).is_integer` are working.https://i10git.cs.fau.de/pycodegen/pystencils/-/merge_requests/65Bugfix: Align calculation of number of ghost layers on GPU with CPU version2019-09-30T14:10:47+02:00Stephan SeitzBugfix: Align calculation of number of ghost layers on GPU with CPU versionFor the calculation of the number of ghostlayers only relative accesses

else:

self.sympy_printer.doprint(node.rhs))
else:
lhs_type = get_type_of_expression(node.lhs)
if type(lhs_type) is VectorType and isinstance(node.lhs, cast_func):
```
It will always prefix const on a declaration. This will not work if dtype is also const since:
```python
def __str__(self):
result = BasicType.numpy_name_to_c(str(self._dtype))
if self.const:
result += " const"
return result
```
So we get something like `const int64_t const`.
I deleted the postfix const to have everything nicely aligned.https://i10git.cs.fau.de/pycodegen/pystencils/-/merge_requests/63Bugfix: this bracket should not be here (collate_types returns single type)2019-09-30T14:10:58+02:00Stephan SeitzBugfix: this bracket should not be here (collate_types returns single type)https://i10git.cs.fau.de/pycodegen/pystencils/-/merge_requests/62Bugfix fields accessed for interpolator access2019-09-30T14:10:31+02:00Stephan SeitzBugfix fields accessed for interpolator accesshttps://i10git.cs.fau.de/pycodegen/pystencils/-/merge_requests/61Kernel wrapper2019-09-26T17:14:29+02:00Stephan SeitzKernel wrapper`KernelWrapper` is cool.
