Line comments with '#' mark at the beginning are compared to
on every 'if' statement although those lines could be notified
as comments at the early stage.
It better skips them, hence we save a few cycles while parsing.
These tests are passed,
# comment type 1
# comment type 2
# comment type 3
#comment type 4
