Just curious if we need this quote handling in explicit linespec's

I thought (though i'm not terribly familiar with c++ linespecs)
that the quotes were for operator+, clashing with foo+offset
and 'something::foo' clashing with file:line stuff,

where it isn't obvious to me the need for it arises when using
explicit locations.
I suppose break -source '/path with spaces/foo.c' -line +42

my main curiosity here is for languages which allow the ' character,
particularly the ML family's usage of type variables[1]. to
discriminate polymorphic functions of the variety break -function
foo('a) vs break -function foo(string).

Given that this isn't really a language gdb currently supports or that
anyone is attempting to add support for (to my knowledge) consider it
with whatever priority you deem appropriate.

I Suppose the above -source style of quoting would push ML support
further in the direction of the ada specific code underneath what i'd
quoted above... hmm
