Developer Skill Sprint: Delphi Anonymous Methods And C++11 Lambdas

I am doing a Developer Skill Sprint this Tuesday, September 22, 2015, titled "Delphi Anonymous Methods and C++11 Lambdas: When to use them and not use them". This blog post contains some of my notes and resource links for my skill sprint.

What will be covered?

• Delphi Anonymous Methods
• C++11 Lambdas
• Parallel Programming Library
• When to use them / When not to use them

Advantages of Anonymous Methods and Lambdas

• Easy way to define and use methods
• Easy to parameterize using code
• Binding of variables in the context of your code
• Avoids direct use of function and procedure pointers
• Doesn't introduce a new name just for a temporary use
• Code clarity: places code closer to where it's called

When To Use Them

• To create a small method that is not meant to be reused
• Method benefits and variable binding/hiding inline in your code
• If a run time library requires them to be used (PPL for example)

When Not To Use Them

• If you are building a library used by another language that does not support Anonymous Methods or Lambdas
