precedence lossage
/pre's*-dens los'*j/ A misunderstanding of {operator
precedence} resulting in unintended grouping of arithmetic or
logical operators when coding an expression. Used
especially of mistakes in C code due to the nonintuitively
low precedence of "&", "|", "^", "<<" and ">>". For example,
the following C expression, intended to test the least
significant bit of x,
x & 1 == 0
is parsed as
x & (1 == 0)
which is always zero (false).
Some lazy programmers ignore precedence and parenthesise
everything. Lisp fans enjoy pointing out that this can't
happen in *their* favourite language, which eschews precedence
entirely, requiring one to use explicit parentheses
everywhere.

Precedence graph
A precedence graph, also named conflict graph and serializability graph, is used in the context of concurrency control in databases.
The precedence graph for a schedule S contains:
- A node for each committed transaction in S
- An arc from Ti to Tj if an action of Ti precedes and conflicts with one of Tj's actions. That is the actions belong to different transactions, at least one of the actions is a write operation, and the actions access the same object (read or write).
