Colon in the string literal leads to a syntax error

Bug Description

Usually I expect that string literals will not break program execution. And I believe it is true for most of the programming languages that any character in the string literal must not lead to syntax error (except of escape sequences)

In the MuranoPL row with a colon (':') like this
      - $log.debug('debug: {0}', param)
leads to syntax error
but if we remove colon like this
      - $log.debug('debug {0}', param)
it become syntactically correct

I believe that such kind of behaviour should be fixed or should be explained in the MuranoPL documentation at least

My script with the colon at the last row which breaks the Syntax

As I understand, comment a whole line should work for YAML but it does not work for MuranoPL

This cannot be fixed without writing our own parser of MuranoPL classes that would be not strictly YAML based. I'm not sure this can be solved even by custom YAML parser because the bug is likely to be in YAML format itself.

Possible workaround:


- $message: 'debug: {0}'
- $log.debug($message, param)

- !yaql "$log.debug( 'debug: {0}', param)"
