Expression of type ExprTuple

from the theory of proveit.logic.booleans

proveit.defaults.automation = False # This will speed things up.
proveit.defaults.inline_pngs = False # Makes files smaller.

# import Expression classes needed to build the expression

# build up the expression from sub-expressions

# check that the built expression is the same as the stored expression
assert expr == stored_expr
