I heard that they added a JIT compiler somewhat recently. But I'm not sure if there's any kind of "true" compiler (or at least linter?), that can find your basic errors prior to runtime.
I used to dabble a lot with Tcl back in the 1990's and early 2000's. I eventually moved into Lisp to scratch that side-project itch, mostly just because I wanted to find more mistakes at build-time than runtime.
Does it allow for ahead of time compilation to bytecode? With build-time reporting of errors in the source code?
Source code is converted to bytecode on the procedure level, not the program level, so there's no program-wide checks for consistency. It's done at runtime.
There are some officially unsupported tools built in to the interpreter that let you dump bytecode of compiled procedures and reload it. You'd have to roll your own dumping and loading scripts if you wanted to deliver an entire program using those tools.
As a linter, I used nagelfar (http://nagelfar.sourceforge.net/). I had it set-up in vim with Syntastic. From what I remember it worked OK, definitely helped compared to no linting.
