Overly long lambda expression

Reports lambda expressions whose number of statements exceeds the specified maximum.

Lambda expressions that are too long may be confusing, and it is often better to extract the statements into a separate method.

The following statements are not counted:

empty statements (semicolons)
block statements
for loop initialization statements, that is, int i = ... within a for(int i = ...;...) statement
for loop update statements, that is, i += 2 within a for(int i = ...;...; i += 2) statement
