string shell pattern match

[Robert Sander]

Hi,

according to the documentation for BIRD 1.6 it should be possible to use
"shell patterns" with the ~ operator on strings:

https://bird.network.cz/?get_doc&v=16&f=bird-5.html#ss5.2

I tried to apply this within a filter but the expression does not match:

if ifname ~ "bond0.4[2345]" then {
  reject;
}

I can only match if I "unroll" the expression and create four different
if statements.

What does "shell pattern" from the documentation mean in this case?
Are [ and ] not valid here?

Regards
