Brainstorm:

To Do

• cover more cases , not only concatenation , printf and sprintf , like addition and join . (...where do I find a complete list?)
• test false positives
• make SIG handler collaborating with older hooks, like for diagnostics
• test package variables
• test global variables ,symbols, barewords
• cover slices like @a[0..2]
• test with different Perl versions in perlbrew
• handle call from filescope and eval

* 17.4.2017

• handle multiple statements in same line

Nice to Have

• report original source line too
• patch B::Deparse instead of parsing string output
• add hooks for further customization by user
• handle tied variables
