| HrBollermann | i need advice. how could i remove the wetness in the grammar? | 09:33 | |
| www.reddit.com/r/adventofcode/comm...?context=3 | |||
| i mean the 5 lines that are basically the same, I feel I should be able to abtract those | 09:34 | ||

| MasterDuke | moritz_ is the person to ask | 09:36 | |
| HrBollermann summons the arcane underscore devourer | 09:42 | ||
| moritz_ | wetness? | 10:19 | |
| all I can say is that the grammar engine isn't doing a lot of work there, so going without it might be easier :D | 10:34 | ||
| one could try to generalize the various parens matchers, something like token paired($open, $close) { $open { $*rep.push: $close } ~ $close <balanced> { $*rep.pop } } | 10:35 | ||
| dunno if that works | |||

| camelia | OK | ||
| mscha | Ah. | ||
| HrBollermann | @moritz_ wetness, as in repeated patterns in code. as in not being DRY | 10:42 | |

| moritz_ | yeah, what I said, either try a parameterized token, or get rid of the grammar | 11:13 | |
| HrBollermann | i seem to be too daft to figure out how to call the token | 11:19 | |

| a_friend | quick question: how do i forward declare a class? | 12:24 | |
| El_Che | I would use roles | 12:30 | |
| lizmat | a_friend: to answer the question: | 12:33 | |
| m: class A { ... }; class A { has $.foo = 42 }; dd A.new | 12:34 | ||
| camelia | A.new(foo => 42) | ||
| lizmat | but as El_Che said: you should probably think about using roles if you can | ||
| a_friend | i see, thanks for the help | 12:38 | |
| i had seen the stackoverflow answer to this question and assumed that "..." was some pseudocode | |||
| it appears that "..." is some actual syntax | |||
