Suggestion: `Calculator(verbose=False)` should not print (or tqdm) any output

2

The verbose output is helpful to see what's going on and get realtime feedback, but sometimes it's hard to find _my_ output among all of pysipfenn's output. I'd like to...

Currently to ESPEI's fixed configuration datasets, sublattices occupied only by an endmember are represented as _not_ wrapped in a tuple. For example, consider a phase with sublattice model `(A,B):(C,D)`, the...

StateVariable.__getitem__ implementation causes infinite loop when used in SymEngine matrix classes

2

This code produces an infinite loop: ```python from pycalphad import variables as v from symengine import ImmutableDenseMatrix print("X SV") ImmutableDenseMatrix([v.StateVariable("X")]) print('done') ``` I traced it back to the implementation of...

Subclassed Symbols that define `__getitem__` break `DenseMatrix`

2

Here's a self-contained test ```python from symengine import Symbol, DenseMatrix class MySymbol(Symbol): def __getitem__(self, x): pass x = Symbol("x") y = MySymbol("y") DenseMatrix([x]) # works fine DenseMatrix([y]) # SIGSEGV ```...
