Save StringConcat bytecode generation for one-time operation

[franz1981]

This has popup as a bytecode generation operation which can both save memory and CPU time at startup, see

It both save the lambda generation and, most importantly, a useless string concatenation.

Why not just eliminate the string concatenation and keep the lambda? Keeping the lambda means one less class to load from disk.

@dmlloyd I have no strong opinion on this, so I can do it like that as well

👍 it's probably better to keep the fix down to the thing being fixed when possible.
