I have a question wrt error reporting.

with opal 0.11 I get

SyntaxError at /
unexpected token tCOLON
Ruby    /Users/beweiche/.rvm/gems/ruby-2.4.1/gems/parser- in process, line 71
Web    GET localhost/

But no hint, which of my source files caused the error.

one can even see with . the errors are reported in the browser console. But there is also no hint to the errornous position.

@bwl21 It has been greatly improved on master, where the position inside the file is now visible if available, e.g. (see the last line where the filename is "-e":
⤑ bin/opal -e 'foo : bar'                                                              ~/C/opal
-e:1:5: error: unexpected token tCOLON
-e:1: foo : bar
-e:1:     ^
