I know what a language ought to be able to do and where the usual foot-guns are. I haven't even attempted to really learn a language thoroughly since my first one (Perl—and yes, that's probably part of where my brain-damage comes from). It's all the same stuff, more or less. Understand pointers and how things like how OO systems are usually implemented, how stacks work, that kind of thing, and all the languages start to blend together.
99% of the pain in a new language usually ends up being the (often god-awful) tools, platform/SDK bullshit, and learning where the clearest path is incorrect (no no no, the official docs and tutorials say to do it this way, but everyone who knows what's what actually replaces that entire part of the language/first-party libraries with this other library developed & open-sourced by some other company, since the official way is obviously so terrible, and you just have to know that, or notice by reading other people's projects—ahem, looking at you, Android). The language itself is typically nothing.
This has worked out fine for me. It does mean I've gradually grown to hate languages that lack static typing. I don't want to remember or look up things when I can make a quick note and then let the computer remember or look it up for me. I thought that was kind of our whole thing, no? Having computers do stuff for us, when they're able?
