Pattern: Missing braces in for

Issue: -

Description

Usage of braces (rather than parentheses) within a for comprehension means that you don't have to specify a semicolon at the end of every line:

for {      // braces
  t <- List(1,2,3)
  if (i % 2 == 0)
} yield t

is preferred to

for (      // parentheses
  t <- List(1,2,3);
  if (i % 2 == 0)
) yield t

To fix it, replace the () with {}. And then remove the ; at the end of the lines.
