Can't chain two matches in same expression because they define the same caprefs

[jaqx0r]

Expressions like:

getfilename() =~ "abc.log" && /expression/ {

are illegale bcause =~ abc.log and expression both cause capture group 0 to be inserted into the current scope, throwing a compile error.

To work around it, put the expression in an inner block like so:

getfilename)( =~ "abc.log" {
  /expression/ {
...
