Tested on both the latest release(0.3.5-alpha) and on the current latest commit(825f280).

Expected behavior

$ amber -e 'import * from "std/text"; echo replace("\\", "\\", "expected")'
expected
$ amber -e 'import * from "std/text"; echo replace("\\\\", "\\\\", "expected")'
expected

Additional context
This is very similar to #481

I'd like to fix this one before 0.4.0-alpha release. It seems weird that it works. It's some kind of escaping bug

@Mte90 It seems that replacing backslash with the bash substitution does not work at all

Btw I think that we should rename these function so that they're called the same way Javascript's functions are:

• replace
• replace_all
