In our compiler course, we studied call-by-need as an evaluation strategy that delays computing function arguments until they are first used.

Call-by-name is an evaluation strategy whereby an argument to a function is evaluated each time its value is used in the function, and is not evaluated at all if its value is never used.

After the performance, the actors returned for multiple curtain calls to acknowledge the audience's applause.

When disagreements escalate, some people call names instead of discussing the issue calmly.

Many interns are nervous about cold-calling during their first week.

Please join the conference call at 3 PM to discuss the quarterly report.

We scheduled three conference calls for next week to coordinate the product launch.

When debugging the multithreaded application, the engineers examined the call stacks to trace the source of the race condition.

The teacher announced that roll calls would be taken at the start of every class this semester.

To improve performance, the compiler automatically detects and optimizes a tail call when compiling recursive functions.
