It is a good design objective in programming language design to not “reinvent the wheel”, especially when there is no actual benefit in the new construct or syntax.  “Thou shalt not succumb to temptation” should be part of the language designer's mottos (including SRFI writers!).  This has been a guiding principle in the design of Gambit, one example being the DSSSL syntax for keywords.  Note that Gambit has the option to use the DSSSL syntax foo: and the CL syntax :foo, but the default is foo: .
