$ perl5.16.1.exe -Mdiagnostics reallyperlconfusingerror.pl Having no space between pattern and following word is deprecated at reallyperlconfusingerror.pl line 5 (#1) (D syntax) You had a word that isn't a regex modifier immediately following a pattern without an intervening space. If you are trying to use the /le flags on a substitution, use /el instead. Otherwise, add white space between the pattern and following word to eliminate the warning. As an example of the latter, the two constructs: $a =~ m/$foo/sand $bar $a =~ m/$foo/s and $bar both currently mean the same thing, but it is planned to disallow the first form in Perl 5.18. And, $a =~ m/$foo/and $bar will be disallowed too. Bareword found where operator expected at reallyperlconfusingerror.pl +line 5, near "print "a - b -Q" (Might be a runaway multi-line -- string starting on line 3) (#2) (S syntax) The Perl lexer knows whether to expect a term or an ope +rator. If it sees what it knows to be a term when it was expecting to see + an operator, it gives you this warning. Usually it indicates that an operator or delimiter was omitted, such as a semicolon. (Do you need to predeclare print?) String found where operator expected at reallyperlconfusingerror.pl li +ne 5, at end of line (#2) (Missing semicolon on previous line?) syntax error at reallyperlconfusingerror.pl line 5, near "print "a - b + -Q" Can't find string terminator '"' anywhere before EOF at reallyperlconf +usingerror.pl line 5 (#3) (F) Probably means you had a syntax error. Common reasons include +: A keyword is misspelled. A semicolon is missing. A comma is missing. An opening or closing parenthesis is missing. An opening or closing brace is missing. A closing quote is missing. Often there will be another error message associated with the synt +ax error giving more information. (Sometimes it helps to turn on -w. +) The error message itself often tells you where it was in the line +when it decided to give up. Sometimes the actual error is several toke +ns before this, because Perl is good at understanding random input. Occasionally the line number may be misleading, and once in a blue + moon the only way to figure out what's triggering the error is to call perl -c repeatedly, chopping away half the program each time to se +e if the error went away. Sort of the cybernetic version of 20 ques +tions. Uncaught exception from user code: syntax error at reallyperlconfusingerror.pl line 5, near "prin +t "a - b -Q" Can't find string terminator '"' anywhere before EOF at really +perlconfusingerror.pl line 5.
